Description

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

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)

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

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

The _tmp table had the following setting.

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

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

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

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