Peter Shi created HDFS-8219:
-------------------------------
Summary: setStoragePolicy with folder behavior is different after
cluster restart
Key: HDFS-8219
URL: https://issues.apache.org/jira/browse/HDFS-8219
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Peter Shi
Priority: Minor
Reproduce steps.
1) mkdir named /temp
2) put one file A under /temp
3) change /temp storage policy to COLD
4) use -getStoragePolicy to query file A's storage policy, it is same with /temp
5) change /temp folder storage policy again, will see file A's storage policy
keep same with parent folder.
then restart the cluster.
do 3) 4) again, will find file A's storage policy is not change while parent
folder's storage policy changes. It behaves different.
As i debugged, found the code:
in INodeFile.getStoragePolicyID
{code}
public byte getStoragePolicyID() {
byte id = getLocalStoragePolicyID();
if (id == BLOCK_STORAGE_POLICY_ID_UNSPECIFIED) {
return this.getParent() != null ?
this.getParent().getStoragePolicyID() : id;
}
return id;
}
{code}
I think the problem maybe here.
