Subject [jira] [Updated] (HBASE-9775) Client write path perf issues
Date Wed, 16 Oct 2013 18:41:44 GMT

     [ https://issues.apache.org/jira/browse/HBASE-9775?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Elliott Clark updated HBASE-9775:
---------------------------------

    Attachment: job_run.log

here's the logs.  The RS's are running G1GC so there should be no issues with GC pausing.

I'm seeing this as the pause times:
2013-10-16T10:19:23.182-0700: [GC pause (young), 0.10152600 secs]

All of the boxes are on 10 gig.

I ran:

{code}
hbase org.apache.hadoop.hbase.test.IntegrationTestBigLinkedList --monkey calm Loop 2 154 25000000
IntegrationTestBigLinkedList 77 > job_run.log  2>&1
{code}

So there should be 2 clients per region server.
