It provides the ability to group the result set on one or more columns (groupBy families). It computes statistics (max, min, sum, count, sum of squares, number missing) for a second column, called the stats column. To use, I've provided two implementations. 1. In the first, you specify a single group-by column and a stats field: statsMap = gbc.getStats(tableName, scan, groupByFamily, groupByQualifier, statsFamily, statsQualifier, statsFieldColumnInterpreter); The result is a map with the Group By column value (as a String) to a GroupByStatsValues object. The GroupByStatsValues object has max,min,sum etc. of the stats column for that group. 2. The second implementation allows you to specify a list of group-by columns and a stats field. The List of group-by columns is expected to contain lists of {column family, qualifier} pairs. statsMap = gbc.getStats(tableName, scan, listOfGroupByColumns, statsFamily, statsQualifier, statsFieldColumnInterpreter); The GroupByStatsValues code is adapted from the Solr Stats component. -- This message is automatically generated by JIRA.

Master can fail if ZooKeeper session expires Key: HBASE-5549 URL: https://issues.apache.org/jira/browse/HBASE-5549 Project: HBase Issue Type: Bug Components: master, zookeeper Affects Versions: 0.96.0 Environment: all Reporter: nkeywal Assignee: nkeywal Priority: Minor There is a retry mechanism in RecoverableZooKeeper, but when the session expires, the whole ZooKeeperWatcher is recreated, hence the retry mechanism does not work in this case. This is why a sleep is needed in TestZooKeeper#testMasterSessionExpired: we need to wait for ZooKeeperWatcher to be recreated before using the connection. This can happen in real life, it can happen when: - master zookeeper starts - zookeeper connection is cut - master enters the retry loop - in the meantime the session expires - the network comes back, the session is recreated - the retries continues, but on the wrong object, hence fails. -- This message is automatically generated by JIRA.

This can be changed, but requires a lot of modifications in these classes (likely adding a class in the middle of the hierarchy, something like that). Anyway, non connected client will always be really slower, because it's a tcp connection, and establishing a tcp connection is slow. - having a link between ZK and all the client seems to make sense for some Use Cases. However, it won't scale if a TCP connection is required for every client - if we move the table descriptor part away from the client, we need to find a new place for it. - we will have the same issue if HBaseAdmin (for both ZK Master), may be we can put a timeout on the connection.

One of them being that there is a limit on the number of connection that ZK can manage. Stack was suggesting as well to remove the link to master from HConnection. There are choices to be made considering the existing API (that we don't want to break). The first patches I will submit on hadoop-qa should not be committed: they are here to show the progress on the direction taken. ZooKeeper is used for: - public getter, to let the client do whatever he wants, and close ZooKeeper when closing the connection = we have to deprecate this but keep it. - read get master address to create a master = now done with a temporary zookeeper connection - read root location = now done with a temporary zookeeper connection, but questionable. Used in public function locateRegion. To be reworked. - read cluster id = now done once with a temporary zookeeper connection. - check if base done is available = now done once with a zookeeper connection given as a parameter - isTableDisabled/isTableAvailable = public functions, now done with a temporary zookeeper connection. - Called internally from HBaseAdmin and HTable - getCurrentNrHRS(): public function to get the number of region servers and create a pool of thread = now done with a temporary zookeeper connection - Master is used for: - getMaster public getter, as for ZooKeeper = we have to deprecate this but keep it. - isMasterRunning(): public function, used internally by HMerge HBaseAdmin - getHTableDescriptor*: public functions offering access to the master. = we could make them using a temporary master connection as well. Main points are: - hbase class for ZooKeeper; ZooKeeperWatcher is really designed for a strongly coupled architecture ;-). This can be changed, but requires a lot of modifications in these classes (likely adding a class in the middle of the hierarchy, something like that). Anyway, non connected client will always be really slower, because it's a tcp connection, and establishing a tcp connection is slow. - having a link between ZK and all the client seems to make sense for some Use Cases. However, it won't scale if a TCP connection is required for every client - if we move the table descriptor part away from the client, we need to find a new place for it. - we will have the same issue if HBaseAdmin (for both ZK Master), may be we can put a timeout on the connection. That would make the whole system

[jira] [Updated] (HBASE-4818) HBase Shell - Add support for formatting row keys before output
[ https://issues.apache.org/jira/browse/HBASE-4818?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Ben West updated HBASE-4818: Attachment: hbase-4818.patch Attaching a patch which includes: 1. The ability to specify a custom formatter on the command line 2. A sample custom formatter which reverses the keys before printing them in a scan You can use the new formatter by doing {code} hbase shell --format=Shell::Formatter::ReverseID.new {code} We have an existing shell variable (JRUBY_OPTS) which you can set in your config script to persist your options, as Lars suggested. I'm not sure how to implement Eran's suggestion of per-table formatters using the command line; maybe we should deprecate the command line option since it doesn't do anything anyway and store this in .irbrc. Also, the reverse ID formatter works by a kind of hack. I'd like to hear from people more familiar with the shell on how to make this better.

Example: scan 'stats', { ROWFORMATTER = MyRowFormatter.new } The row formatter simply gets the bytes array key and formats it to a string. Its an easy change tomake with simple monkey-patching of the shell commands but I would be happy to see it as part of the shell itself. -- This message is automatically generated by JIRA.

At table creation time, one can specify that the table be stored in columnar-encoded fashion. A HFile will have information in the FixedFileTrailer that specifies whether the data inside the hfile is in columnar-format. A single HFileBlock will have four column-entity: all the rowkeys will be laid out first, followed by all the cf, followed by all the column names, followed by the timestamps, followed by the memstoreTS, followed by all the values. If 'prefix-encoding' is enabled, then each column-entity will be prefix encoded individually. If compression (lzo, gz, etc) is enabled, the entire HFileBlock will be compressed accordingly. Prefix-encoding will work well for the rowkey entity and the column-family entity. The column name entity may need to be sorted and then prefix encoded. The timestamp entity may need special kind of encoding. One option (suggested by a co-worker Chip Turner) is to take the first timestamp as the base and xor it with each of the following timestamps (thus, zeroing out the common bits) and then storing it. Another option is to find the minimum timestamp in the block and then store diffs from that minimum value. Yet another option is to make Jan-01-2012 as the hbase-epoch and store the difference from that number.

Can we can organize these kvs on the disk in a better way so that we get much greater compression ratios? One option (thanks Prakash) is to store all the keys in the beginning of the block (let's call this the key-section) and then store all their corresponding values towards the end of the block. This will allow us to not-even decompress the values when we are scanning and skipping over rows in the block. Any other ideas? -- This message is automatically generated by JIRA.
