Subject [jira] [Updated] (CASSANDRA-8978) CQLSSTableWriter causes ArrayIndexOutOfBoundsException
Date Tue, 17 Mar 2015 14:17:38 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-8978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas Borg Salling updated CASSANDRA-8978:
-------------------------------------------
    Description: 
On long-running jobs with CQLSSTableWriter preparing sstables for later bulk load via sstableloader,
occassionally I get the sporadic error shown below.

I can run the exact same job again - and it will succeed or fail with the same error at another
location in the input stream. The error is appears to occur "randomly" - with the same input
it may occur never, early or late in the run with no apparent logic or system.

I use five instances of CQLSSTableWriter in the application (to write redundantly to five
different tables). But these instances do not exist at the same time; and thus never used
concurrently.
