[jira] [Created] (HDFS-12613) Native EC coder should implement release() as idempotent function.

Lei (Eddy) Xu created HDFS-12613:
------------------------------------

             Summary: Native EC coder should implement release() as idempotent function.
                 Key: HDFS-12613
                 URL: https://issues.apache.org/jira/browse/HDFS-12613
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: erasure-coding
    Affects Versions: 3.0.0-beta1
            Reporter: Lei (Eddy) Xu


Recently, we found native EC coder crashes JVM because {{NativeRSDecoder#release()}} being called multiple times (HDFS-12612 and HDFS-12606). 

We should strength the implement the native code to make {{release()}} idempotent  as well.
