Subject [jira] [Commented] (HBASE-14362) org.apache.hadoop.hbase.master.procedure.TestWALProcedureStoreOnHDFS is super duper flaky
Date Tue, 29 Sep 2015 00:59:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14934427#comment-14934427

Heng Chen commented on HBASE-14362:

If i set param 
    conf.setInt("hbase.procedure.store.wal.max.roll.retries", 1);
    conf.setInt("hbase.procedure.store.wal.sync.failure.roll.max", 1);

This issue will be reproduced locally.  

I think the reason is, as original logic  
 store.insert(new TestProcedure(i, -1), null);

after we restart dn,  we insert immediately,  when dn is not started fully, the testcase will

So we use {{waitForNumReplicas(3)}} before insert,  in {{waitForNumReplicas(3)}} it will wait
dn start fully. 

after do that,  the testcase will not failed again locally.

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