[jira] [Commented] (HAWQ-1506) Fix multi-append bug

    [ https://issues.apache.org/jira/browse/HAWQ-1506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16098118#comment-16098118 ] 

Hongxu Ma commented on HAWQ-1506:
---------------------------------

After read code of HDFS (hadoop-common/src/main/java/org/apache/hadoop/crypto/CryptoOutputStream.java):
We should do updateEncryptor(calculate a correct counter for AES-CTR) when open a file.

It should fix this bug.
