Agreed that we should not change the declared interface for TRR in patch releases. Ugly, but we can rethrow as RuntimeException or ignore in 1.1 and before. I think this is also a blocker: https://issues.apache.org/jira/browse/HBASE-14474 Enis On Wed, Sep 23, 2015 at 3:50 PM, Nick Dimiduk

Re: Table regions are written in wrong path in HDFS

Normally this path: /hbase/data/default/TestTable/TestTable/ d5b64ad96deb3b47467db97669c009fb should be /hbase/data/default/TestTable/d5b64ad96deb3b47467db97669c009fb. Meaning that the table descriptor somehow was written under the wrong folder (there should be only one TestTable in the path).

Re: HA reads properties

Some of these properties got changed, deprecated or new ones added between different apache versions. The apache documentation lists the latest configuration examples which should work with hbase-1.1+. Enis On Thu, Nov 19, 2015 at 8:49 AM, Melvin Kanasseril < melvin.kanasse...@sophos.com> wrote:

Re: Question regarding the regionservers file on the HBase master

The regionservers file is used only by the start-hbase.sh and stop-hbase.sh kind of scripts. That is why the documentation is referring to as "if you rely on ssh to start your daemons". These scripts executes the start or stop daemon request using SSH. That is also why you need to have a list of

Re: Enabling stripe compaction without disabling table

Disabling the table should not be needed. From the stripe compaction perspective, deploying this in a disabled table versus in an online alter table is not different at all. The "hbase.online.schema.update.enable" property was fixing some possible race conditions that were fixed long time ago. We

Re: Scan.setMaxResultSize and Result.isPartial

You should probably read https://blogs.apache.org/hbase/entry/scan_improvements_in_hbase_1 first. In HBase-1.1 and later code bases, you can call Scan.allowPartialResults() to instruct the ClientScanner to give you partial results. In this case, you can use Result.isPartial() to stitch together

Re: maybe waste on blockCache

LRUBlock cache does not reserve the space for the in_memory tier. The space is used for other tiers as well as long as there is space. You can read the code at LRUBlockCache.evict() to learn more. Enis On Thu, Jun 16, 2016 at 1:21 AM, WangYQ wrote: > in hbase

Re: Row length is 0 at org.apache.hadoop.hbase.client.Mutation.checkRow(Mutation.java:503)

The row key byte[] you are passing in Get() has a length of 0. HBase data model does not allow 0-length row key, it should be at least 1 byte. 0-byte row key is reserved for internal usage (to designate empty start key and end keys). In your storm topology, you are probably passing a row key that

Re: Compaction settings per table

For compaction configurations, you can also set it per table OR even per column family. In java, you can use HTableDescriptor.setConfiguration() or HColumnDescriptor.setConfiguration() to set the specific configuration values that overrides the ones set in hbase-site.xml. For compaction and

Re: [Query:]Table creation with column family in Phoenix

Phoenix maintains a column with empty value, because unlike a row-oriented RDBMS, a NULL column is not represented explicitly in HBase, but implicitly where the cell is not in HBase at all. Here is the explanation from phoenix.apache.org: For CREATE TABLE, an empty key value will also be added

Re: How to find versions 0.95 through 1.3 of the HBase reference (book)?

We do not publish per-release docs other than the master and 0.94. 0.94 is for a special reason since 0.96+ contains some major changes. The release artifacts for every release contains the book in the tarball if you want to browse through. Enis On Wed, Mar 2, 2016 at 4:00 PM, Cosmin Lehene
