[jira] [Commented] (SPARK-8428) TimSort Comparison method violates
its general contract with CLUSTER BY
[ https://issues.apache.org/jira/browse/SPARK-8428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14633007#comment-14633007 ]
Reynold Xin commented on SPARK-8428:

> Key: SPARK-8428
> URL: https://issues.apache.org/jira/browse/SPARK-8428
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 1.4.0
> Environment: Oracle Java 7
> Reporter: Nathan McCarthy
>
> Running an SQL query that has a sub query and multiple left joins fails when there is a CLUSTER BY (which implies a sortBy). This gives the following stack trace;
> {code}
> Job aborted due to stage failure: Task 118 in stage 4.0 failed 4 times, most recent failure: Lost task 118.3 in stage 4.0 (TID 18392, node142): java.lang.IllegalArgumentException: Comparison method violates its general contract!
