Subject [jira] [Created] (ACCUMULO-3912) Random walk sets random config on default namespace

Keith Turner created ACCUMULO-3912:
--------------------------------------

             Summary: Random walk sets random config on default namespace
                 Key: ACCUMULO-3912
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3912
             Project: Accumulo
          Issue Type: Bug
            Reporter: Keith Turner


While running random walk test for 1.6.3, the following failure happened.

{noformat}
Caused by: java.lang.Exception: Props not equals ST_index_worker4_3842_1435004444639 ST_index_worker4_3842_1435004444639_tmp
        at org.apache.accumulo.test.randomwalk.shard.ExportIndex.visit(ExportIndex.java:106)
{noformat}

I looked at the two tables config in the shell and found the following property differed.


{noformat}
default    | table.compaction.minor.idle ............... | 5m
default    | table.compaction.minor.logs.threshold ..... | 3
{noformat}

The _tmp table had the following setting.

{noformat}
default    | table.compaction.minor.idle ............... | 5m
table      |    @override .............................. | 178299085
default    | table.compaction.minor.logs.threshold ..... | 3
{noformat}

I grepped all the random walkers logs and found the following :

{noformat}
[11] 21:18:42 [SUCCESS] worker0
22 20:33:57,007 [concurrent.Config] DEBUG: Setting table.compaction.minor.idle on namespace
 to 178299085
{noformat}

So {{concurrent.Config}} updated props on a random namepace and caused the shard test to fail,
it should not do this.
