Yuanbo Liu commented on HDFS-13724:
-----------------------------------
how about implementing a new command called "-find" to get the results?
> Storage Tiering Show Paths with Policies applied
> ------------------------------------------------
>
> Key: HDFS-13724
> URL: https://issues.apache.org/jira/browse/HDFS-13724
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Hari Sekhon
> Priority: Major
>
> Improvement Request to add an hdfs storagepolicies command to find paths for
> which storage policies have been applied.
> Right now you must explicitly query a single directory to get its policy to
> determine if one has been applied, but if another hadoop admin has configured
> policies on anything but trivially obvious paths such as /archive then there
> is no way to find which paths have policies applied to them other than by
> querying every single directory and subdirectory one by one which might
> potentially have a policy, eg:
> {code:java}
> hdfs storagepolicies -getStoragePolicy -path /dir3/subdir1
> hdfs storagepolicies -getStoragePolicy -path /dir2
> hdfs storagepolicies -getStoragePolicy -path /dir3
> hdfs storagepolicies -getStoragePolicy -path /dir3/subdir1
> hdfs storagepolicies -getStoragePolicy -path /dir3/subdir2
> hdfs storagepolicies -getStoragePolicy -path /dir3/subdir3
> ...
> hdfs storagepolicies -getStoragePolicy -path /dirN
> ...
> hdfs storagepolicies -getStoragePolicy -path /dirN/subdirN/subsubdirN
> ...{code}
> In my current environment for example, a policy was configured for /data/blah
> which doesn't show when trying
> {code:java}
> hdfs storagepolicies -getStoragePolicy -path /data{code}
> and I had no way of knowing that I had to do:
> {code:java}
> hdfs storagepolicies -getStoragePolicy -path /data/blah{code}
> other than trial and error of trying every directory and every subdirectory
> in hdfs.
