> TestBlockPoolManager unit test fails with the following error message using IBM java:
> testFederationRefresh(org.apache.hadoop.hdfs.server.datanode.TestBlockPoolManager)  Time
elapsed: 27 sec  <<< FAILURE!
> org.junit.ComparisonFailure: expected:<stop #[1
> refresh #2]
> > but was:<stop #[2
> refresh #1]
> >
> The root cause is:
> (1)if we want to remove the first NS, keep the second NS, it should be conf.set(DFSConfigKeys.DFS_NAMESERVICES,
ns2), not conf.set(DFSConfigKeys.DFS_NAMESERVICES, ns1).
> (2)Since HashMap & HashSet store the data in the random order way, so in ibm java
& Oracle java, HashMap get the random order <key, value> that causing the random
ns1&ns2 value.  So in the code, it should use LinkedHashMap & LinkedHashSet to keep
the original order.
