Subject [jira] [Created] (HBASE-16558) IntegrationTestBulkLoad failing during linked list check
Date Sun, 04 Sep 2016 05:39:21 GMT
Dima Spivak created HBASE-16558:

             Summary: IntegrationTestBulkLoad failing during linked list check
                 Key: HBASE-16558
                 URL: https://issues.apache.org/jira/browse/HBASE-16558
             Project: HBase
          Issue Type: Bug
          Components: integration tests
    Affects Versions: 1.1.5, 2.0.0, 1.1.6
            Reporter: Dima Spivak

Noticed this while testing 1.1.6 RC2, but then also reproduced it against 1.1.5 and master
(more testing to come, but I wanna get a JIRA open to reference in the RC vote). When running
{{IntegrationTestBulkLoad}} on a 5-node {{cluserdock}}-based deployment (seen with no monkey
 as well as with the {{unbalance}} monkey, which is the only one I've tried), the test fails
during the checking phase with a set of messages like the following:
2016-09-04 05:27:52,313 INFO  [main] mapreduce.Job: Task Id : attempt_1472966120303_0006_m_000007_0,

[Here's the line of code that causes problems|https://github.com/apache/hbase/blob/branch-1.1/hbase-it/src/test/java/org/apache/hadoop/hbase/mapreduce/IntegrationTestBulkLoad.java#L603],
but I'll need to dig further to understand what's going on.
