Doris Gu updated HDFS-7601:
---------------------------
Status: Patch Available (was: Open)
This patch includes:
1.GetNameServiceUris from config in DFSUtil.java adds functions to ignore the
"/" in the end of uris.
2.Add corresponding test to make sure that an HA URI and the default URI whose
difference is ending with or without "/" doesn't result in multiple entries
being returned.
Actually speaking,this problem comes from my own not so well config. I use
"hdfs://haCluster/" for "fs.defaultFS" in core-site.xml. I can easily avoid
this problem by make this config value to be "hdfs://haCluster", but someone
else may give the similar value, so I propose this patch.
> Operations(e.g. balance) failed due to deficient configuration parsing

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer & mover
> Affects Versions: 2.6.0, 2.3.0
> Reporter: Doris Gu
> Assignee: Doris Gu
> Priority: Minor
> Labels: patch
>
> Some operations, for example,balance,parses configuration(from
> core-site.xml,hdfs-site.xml) to get NameServiceUris to link to.
> Current method considers those end with or without "/" as two different
> uris, then following operation may meet errors.
> bq. [hdfs://haCluster, hdfs://haCluster/] are considered to be two different
> uris which actually the same.
