Subject [jira] [Commented] (HBASE-13154) Add support for mob in TestAcidGuarantees and IntegrationTestAcidGuarantees
Date Thu, 05 Mar 2015 06:53:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13154?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14348268#comment-14348268

Jonathan Hsieh commented on HBASE-13154:

[~anoop.hbase], I'm a little confused by your comment.  

Setting -DuseMob makes checks to make sure hfile v3 is being used and either creates a the
new table or uses the existing table and then modifies the first cf such that the mob threshold
is 4 and mob is enabled.

For example, to run the integration test in a mode that exercises the mob feature, I use this
command line (where RUNMS and MONKEY are set).  
$HBASE_HOME/bin/hbase org.apache.hadoop.hbase.IntegrationTestAcidGuarantees -DuseMob=true
-Dmillis=$RUNMS -m $MONKEY

> Adding support to run acid guarantees tests on data that is primarily in the mob path.
> We essentially set the mob size to be very small (4) and run the same test.  This is
activated using the -DuseMob=true tool style command line arg.
