Subject [jira] [Commented] (HBASE-8803) region_mover.rb should move multiple regions at a time
Date Tue, 25 Feb 2014 21:17:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13912077#comment-13912077

stack commented on HBASE-8803:

I tried it boss.  After fixing the below.....

-distMode=`$bin/hbase org.apache.hadoop.hbase.util.HBaseConfTool hbase.cluster.distributed
| head -n 1`
+distMode=`$bin/hbase org.apache.hadoop.hbase.util.HBaseConfTool --config "${HBASE_CONF_DIR}
hbase.cluster.distributed | head -n 1`

(there is a '"' missing after the HBASE_CONF_DIR).... it worked very nicely. 

The change in HBaseConfTool.java doesn't look right.  You are doing the parse yourself and
presuming I want the hbase-site.xml file only.

What if you change this:

.... $bin/hbase org.apache.hadoop.hbase.util.HBaseConfTool --config "${HBASE_CONF_DIR}  

to be:

HBASE_CONF_DIR=${HBASE_CONF_DIR} $bin/hbase org.apache.hadoop.hbase.util.HBaseConfTool ....


Might have to check for an empty HBASE_CONF_DIR and set it if not set?   As is done in the
shell scripts.

Thanks JMS.

> When there is many regions in a cluster, rolling_restart can take hours because region_mover
is moving the regions one by one.
