Subject [jira] [Updated] (HBASE-17489) ClientScanner may send a next request to a RegionScanner which has been exhausted
Date Thu, 19 Jan 2017 08:53:26 GMT

     [ https://issues.apache.org/jira/browse/HBASE-17489?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Duo Zhang updated HBASE-17489:
------------------------------
    Attachment: HBASE-17489.patch

TestClientScanner fails but I think the testcase itself is a little strange so disable it
to see if there are other failures. If not then I will try to modify the testcase itself.

And I think it is better to integrate the 'close scanner automatically at RS side if no more
resuls' feature in this patch rather than in HBASE-17045. Will upload patches with this feature
later if the client side modification can pass the pre commit check.

> Found it when implementing HBASE-17045. Seems the final result of the scan is correct
but no doubt the logic is broken. We need to fix it to stop things get worse in the future.
