This -release contains changes from more then 40 issues, comprised of bug-fixes, -performance improvements, build quality improvements, and more. See -[JIRA][JIRA_181] for a complete list. - - -Below are resources for this release: - -* [User Manual][user_manual] -* [Javadocs][javadocs] -* [Examples][examples] - -In the context of Accumulo's [Semantic Versioning][semver] [guidelines][api], -this is a "minor version". This means that new APIs have been created, some -deprecations may have been added, but no deprecated APIs have been removed. -Code written against 1.7.x should work against 1.8.0 -- binary compatibility -has been preserved with one exception of an already-deprecated Mock Accumulo -utility class. As always, the Accumulo developers take API compatibility -very seriously and have invested much time to ensure that we meet the promises set forth to our users. - -## Major Changes - -### Problem with scans right after minor compaction - -A bug was found when 2 or more concurrent scans run on a tablet that -has just undergone minor compaction. The minor compaction thread -writes the in-memory map to a local temporary rfile and tries to -switch the current iterators to use it instead of the native map. The -iterator code in the scan thread may also switch itself to use the local -temporary rfile it if notices it before the minor compaction threads -performs the switch. The bug happened shortly after the switch when -one of the iterator threads will get a NegativeArraySizeException. -See [ACCUMULO-4483][ACCUMULO_4483] for more info. - -### Tablet Server Performance Improvement - -[ACCUMULO-4458][ACCUMULO_4458] mitigated some contention on the Hadoop -configuration instance backing the XML configs read for SiteConfiguration. -This should improve overall Tablet Server performance. - -### Synchronization issue with deep copies of sources - -Deep copies of iterator sources were not thread safe and threw -exceptions, mostly down in the ZlibDecompressor library. The real bug -was in the BoundedRangeFileInputStream. The read() method -synchronizes on the underlying FSDataInputStream, however the -available() method did not. See [ACCUMULO-4391][ACCUMULO_4391]. - -### System permission bug in Thrift Proxy - -The Accumulo Proxy lacked support for the following system permissions: - -* System.CREATE_NAMESPACE -* System.DROP_NAMESPACE -* System.ALTER_NAMESPACE -* System.OBTAIN_DELEGATION_TOKEN - -Ticket is [ACCUMULO-4519][ACCUMULO_4519]. - -### Shell compaction file selection options can block - -The block happens when the tablet lock is held. The tablet lock is -meant to protect changes to the tablets internal metadata, and -blocking operations should not occur while this lock is held. The -compaction command has options to select files based on some -criteria, some of which required blocking operations. This issue is -fixed in [ACCUMULO-4572][ACCUMULO_4572]. - -### HostRegexTableLoadBalancer used stale information - -The HostRegexTableLoadBalander maintains an internal mapping of tablet -server pools and tablet server status. It was updated at a -configurable interval initially as an optimization. Unfortunately it -had the negative side effect of providing the assignment and balance -operations with stale information. This lead to a constant shuffling -of tablets. The configuration property was removed so that -assign/balance methods get updated information every time. See -[ACCUMULO-4576][ACCUMULO_4576]. - -### Modify TableOperations online/offline to check for table state - -The table operations online and offline operations execute as a fate -operation.

This +release contains changes from more then 40 issues, comprised of bug-fixes, +performance improvements, build quality improvements, and more. See +[JIRA][JIRA_181] for a complete list. + + +Below are resources for this release: + +* [User Manual][user_manual] +* [Javadocs][javadocs] +* [Examples][examples] + +In the context of Accumulo's [Semantic Versioning][semver] [guidelines][api], +this is a "minor version". This means that new APIs have been created, some +deprecations may have been added, but no deprecated APIs have been removed. +Code written against 1.7.x should work against 1.8.0 -- binary compatibility +has been preserved with one exception of an already-deprecated Mock Accumulo +utility class. As always, the Accumulo developers take API compatibility +very seriously and have invested much time to ensure that we meet the promises set forth to our users. + +## Major Changes + +### Problem with scans right after minor compaction + +A bug was found when 2 or more concurrent scans run on a tablet that +has just undergone minor compaction. The minor compaction thread +writes the in-memory map to a local temporary rfile and tries to +switch the current iterators to use it instead of the native map. The +iterator code in the scan thread may also switch itself to use the local +temporary rfile it if notices it before the minor compaction threads +performs the switch. The bug happened shortly after the switch when +one of the iterator threads will get a NegativeArraySizeException. +See [ACCUMULO-4483][ACCUMULO_4483] for more info. + +### Tablet Server Performance Improvement + +[ACCUMULO-4458][ACCUMULO_4458] mitigated some contention on the Hadoop +configuration instance backing the XML configs read for SiteConfiguration. +This should improve overall Tablet Server performance. + +### Synchronization issue with deep copies of sources + +Deep copies of iterator sources were not thread safe and threw +exceptions, mostly down in the ZlibDecompressor library. The real bug +was in the BoundedRangeFileInputStream. The read() method +synchronizes on the underlying FSDataInputStream, however the +available() method did not. See [ACCUMULO-4391][ACCUMULO_4391]. + +### System permission bug in Thrift Proxy + +The Accumulo Proxy lacked support for the following system permissions: + +* System.CREATE_NAMESPACE +* System.DROP_NAMESPACE +* System.ALTER_NAMESPACE +* System.OBTAIN_DELEGATION_TOKEN + +Ticket is [ACCUMULO-4519][ACCUMULO_4519]. + +### Shell compaction file selection options can block + +The block happens when the tablet lock is held. The tablet lock is +meant to protect changes to the tablets internal metadata, and +blocking operations should not occur while this lock is held. The +compaction command has options to select files based on some +criteria, some of which required blocking operations. This issue is +fixed in [ACCUMULO-4572][ACCUMULO_4572]. + +### HostRegexTableLoadBalancer used stale information + +The HostRegexTableLoadBalander maintains an internal mapping of tablet +server pools and tablet server status. It was updated at a +configurable interval initially as an optimization. Unfortunately it +had the negative side effect of providing the assignment and balance +operations with stale information. This lead to a constant shuffling +of tablets. The configuration property was removed so that +assign/balance methods get updated information every time. See +[ACCUMULO-4576][ACCUMULO_4576]. + +### Modify TableOperations online to check for table state + +The table operations online operation executes as a fate +operation. If a transaction lock for the table is currently held, +this operation will block even if no action is needed. +[ACCUMULO-4574][ACCUMULO_4574] changes the behavior of the online +operation to a NOOP if the table is already in the requested state. +This returns immediately without queuing a fate operation. + +## Other Notable Changes + +* [ACCUMULO-4488][ACCUMULO_4488] Fix gap in user manual on Kerberos for clients +* [ACCUMULO-2724][ACCUMULO_2724] CollectTabletStats had multiple -t parameter +* [ACCUMULO-4431][ACCUMULO_4431] Log what random is chosen for a tserver. +* [ACCUMULO-4494][ACCUMULO_4494] Include column family seeks in the Iterator Test Harness +* [ACCUMULO-4549][ACCUMULO_4549] Remove duplicate init functions in TabletBalancer +* [ACCUMULO-4467][ACCUMULO_4467] Random Walk broken because of unmet dependency on commons-math +* [ACCUMULO-4578][ACCUMULO_4578] Cancel compaction FATE operation does not release namespace lock +* [ACCUMULO-4505][ACCUMULO_4505] Shell still reads accumulo-site.xml when using Zookeeper CLI options +* [ACCUMULO-4535][ACCUMULO_4535] HostRegexTableLoadBalancer fails with NullPointerException +* [ACCUMULO-4575][ACCUMULO_4575] Concurrent table delete operations leave orphan fate transaction locks + +## Upgrading + +Upgrades from 1.7 to 1.8 are possible with little effort as no changes were made at the data layer and RPC changes +were made in a backwards-compatible way.
