Subject [jira] [Updated] (CASSANDRA-7947) Change error message when RR times out
Date Tue, 16 Sep 2014 22:54:34 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-7947?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Brandon Williams updated CASSANDRA-7947:
----------------------------------------
    Description: When a quorum request detects a checksum mismatch, it then reads the data
to repair the mismatch by issuing a request at CL.ALL to the same endpoints  (SP.fetchRows)
 If this request in turn times out, this delivers a TOE to the client with a misleading message
that mentions CL.ALL, possibly causing them to think the request has gone cross-DC when it
has not, it was just slow due to timing out.  (was: When a quorum request detects a checksum
mismatch, it then reads the data to repair the mismatch by issuing a request at CL.ALL to
the same endpo ints  (SP.fetchRows)  If this request in turn times out, this delivers a TOE
to the client with a misleading message that mentions CL.ALL, possibly causing them to think
the request has gone cross-DC when it has not, it was just slow due to timing out.)
