[jira] [Updated] (HBASE-15806) An endpoint-based export tool

["Appy (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-15806?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Appy updated HBASE-15806:
-------------------------
    Release Note: 
org.apache.hadoop.hbase.coprocessor.Export
Instructs HBase to dump the contents of table to HDFS in a sequence file
+ replaces MR by endpoint (see org.apache.hadoop.hbase.mapreduce.Export)
+ no large data to be transfered between hbase server and client
+ same command line as org.apache.hadoop.hbase.mapreduce.Export
- user needs to alter table for deploying ExportEndpoint
- user needs to adjust the endpoint timeout for dumping large data
- user needs to get the EXECUTE permission

> The time for exporting table can be reduced, if we use the endpoint technique to export the hdfs files by the region server rather than by hbase client.
> In my experiments, the elapsed time of endpoint-based export can be less than half of current export tool (enable the hdfs compression)
> But the shortcomings is we need to alter table for deploying the endpoint
> any comments about this? thanks
