Ayush Saxena commented on HDFS-13661:
-------------------------------------
Thanks [~tasanuma0829] for the patch!!
{code:java}
- int maxEC=0;
+ int maxEC = 12; // set initial length with default ec-policy,
RS-6-3-1024k
{code}
Not sure about this change.Support for user defined EC policies is also
there.There are chances that their length is less than 12 and the directory on
which we call LS have them only set.Apart from this patch v2 seems good to me.
