Subject [jira] [Resolved] (HBASE-15404) PE: Clients in append and increment are operating serially
Date Sat, 02 Apr 2016 03:16:25 GMT

     [ https://issues.apache.org/jira/browse/HBASE-15404?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Appy resolved HBASE-15404.
--------------------------
    Resolution: Invalid

Clients are still working parallely, except that they all process keys from a same small range
at a time. for eg. fist 0 - 1M, then 1M - 2M, so on..
Thanks stack for explaining.

> On running hbase pe --nomapred increment/append 10,  i see the following output where
it seems like threads are executing operations serially. In the UI too, only one RS is getting
requests at a time.
