Subject [jira] [Commented] (HBASE-12782) ITBLL fails for me if generator does anything but 5M per maptask
Date Thu, 08 Jan 2015 22:22:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14270139#comment-14270139
] 

stack commented on HBASE-12782:
-------------------------------

Seems harder getting 0.98 to fail. Ran twice at 125M/5slots and it passed.  Upped to 250M
and 40 missing references which is also less than I normally see on 1.0.  Trying some more.
 Will go back to 1.0 since easier repro there and hopefully same issue.  Will be back to 0.98
after to make sure any fix covers it too.

> Anyone else seeing this?  If I do an ITBLL with generator doing 5M rows per maptask,
all is good -- verify passes. I've been running 5 servers and had one splot per server.  So
below works:
> HADOOP_CLASSPATH="/home/stack/conf_hbase:`/home/stack/hbase/bin/hbase classpath`" ./hadoop/bin/hadoop
--config ~/conf_hadoop org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList --monkey
serverKilling Generator 5 5000000 g1.tmp
> or if I double the map tasks, it works:
> HADOOP_CLASSPATH="/home/stack/conf_hbase:`/home/stack/hbase/bin/hbase classpath`" ./hadoop/bin/hadoop
--config ~/conf_hadoop org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList --monkey
serverKilling Generator 10 5000000 g2.tmp
> ...but if I change the 5M to 50M or 25M, Verify fails.
> Looking into it.
