Vinayakumar B commented on HDFS-14113:
--------------------------------------
Thanks [~ayushtkn] for the patch.
Please find the comments below.
{code}
+
+ userDefinedAllowed = conf.getBoolean(
+ DFSConfigKeys.DFS_NAMENODE_EC_POLICIES_USSERPOLICIES_ALLOWED_KEY,
+ DFSConfigKeys.
+ DFS_NAMENODE_EC_POLICIES_USSERPOLICIES_ALLOWED_KEY_DEFAULT);
}
{code}
Please correct the Typo.
{code}
public synchronized ErasureCodingPolicy addPolicy(
ErasureCodingPolicy policy) {
+ if (!userDefinedAllowed) {
+ throw new HadoopIllegalArgumentException(
+ "Addition of user defined erasure coding policy is disabled.");
+ }
+
{code}
Instead of throwing {{HadoopIllegalArgumentException}}, can throw
{{UnsuportedOperationException}} with proper message.
