Subject [jira] [Updated] (CASSANDRA-10600) CqlInputFormat throws IOE if the size estimates are zero
Date Thu, 05 Nov 2015 18:46:27 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-10600?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Paulo Motta updated CASSANDRA-10600:
------------------------------------
    Attachment: 10600-v2.txt

LGTM, uploaded v2 version removing unnecessary trailing whitespaces.

(lots of unrelated dtests failures, probably caused by python driver update of CASSANDRA-10365,
but in pair with latest dtest runs: [3.0|http://cassci.datastax.com/view/cassandra-3.0/job/cassandra-3.0_dtest/327/testReport/]
and [trunk|http://cassci.datastax.com/view/trunk/job/trunk_dtest/731/testReport/].

> {{CqlInputFormat.describeSplits}} handles the case of no entry in the 'system.size_estimates'
table but does not handle the situation when there is a zero size estimate in the table. This
can happen if an input job is started immediately after data is added but before the {{SizeEstimatesRecorder}}
has run.
> {{CqlInputFormat.describeSplits}} should handle 0 size estimate in the same manner as
no size estimate and not sub-split but return the full split.
