Subject [jira] [Commented] (HBASE-14362) org.apache.hadoop.hbase.master.procedure.TestWALProcedureStoreOnHDFS is super duper flaky
Date Tue, 15 Sep 2015 16:16:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14745664#comment-14745664
] 

Matteo Bertozzi commented on HBASE-14362:
-----------------------------------------

if you look at the TestWALProcedureStoreOnHDFS code it already say that is flaky in case of
slow machines.
you can bump the value as much as you want, but if the machine is even slower it will fail
again. 
the other downside is that it will slow down runs on faster machines
{code}
    // increase the value for slow test-env
    conf.setInt("hbase.procedure.store.wal.wait.before.roll", 1000);
    conf.setInt("hbase.procedure.store.wal.max.roll.retries", 5);
    conf.setInt("hbase.procedure.store.wal.sync.failure.roll.max", 5);
{code}

this test has been super flaky and we should probably address it.
