Brahma Reddy Battula commented on HDFS-12214:
---------------------------------------------
[~rakeshr] thanks for updating the patch and considering some of my offline
comments.
*Few minor nits:*
1) Now you need add the following while starting the SPS..? just I disabled
{{storagePolicyEnabled}] and executed the {{TestStoragePolicyCommands}},it's
pass.
{noformat}
if (!(storagePolicyEnabled && spsEnabled)) {
LOG.warn(
"Failed to start StoragePolicySatisfier"
+ " since {} set to {} and {} set to {}.",
DFSConfigKeys.DFS_STORAGE_POLICY_ENABLED_KEY, storagePolicyEnabled,
DFSConfigKeys.DFS_STORAGE_POLICY_SATISFIER_ENABLED_KEY, spsEnabled);
}
{noformat}
2) how about having one testcase,when {{DFS_STORAGE_POLICY_ENABLED_KEY}} is
disabled..? if already there,please ignore
3) can you update {{writeUnlock(operationName);}} in
{{org.apache.hadoop.hdfs.server.namenode.FSNamesystem#satisfyStoragePolicy}}
{noformat}
2173 writeUnlock();
{noformat}
4) can we add null check in
{{org.apache.hadoop.hdfs.server.namenode.FSDirSatisfyStoragePolicyOp#unprotectedSatisfyStoragePolicy}}..?
{noformat}
if (inode == null) {
throw new FileNotFoundException("File/Directory does not exist: "
+ iip.getPath());
}
{noformat}
5) can we update statistics ..?
org.apache.hadoop.hdfs.DistributedFileSystem#satisfyStoragePolicy, seperate
jira also ok, as it's not target for this.
{noformat}
statistics.incrementWriteOps(1);
storageStatistics.incrementOpCounter(OpType.SET_STORAGE_POLICY);
{noformat}
May be you can jira Title..?
