Subject [jira] [Commented] (MAPREDUCE-6774) Add support for HDFS erasure code policy to TestDFSIO
Date Tue, 13 Sep 2016 08:06:20 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15486603#comment-15486603
] 

Kai Zheng commented on MAPREDUCE-6774:
--------------------------------------

So given above, the following can then be:
{code}
+    if (storagePolicy != null) {
+      if (!isStoragePolicyValid(storagePolicy, fs)) {
+        return -1;
+      }
{code}
=>
{code}
+    if (storagePolicy != null) {
+      checkStoragePolicy(storagePolicy, fs);
+    }
{code}

> HDFS erasure code policy allows user to store directory and file to predefined erasure
code policies. Currently only 3x replication is supported in TestDFSIO implementation. This
is going to add an new option to enable tests of files with erasure code policy enabled.
