Saijin Huang commented on HIVE-17549:
-------------------------------------
Thanks for reply![~lirui].As we konw,MD5 is weaker than sha-256.it is necessary
to replace md5 hash by sha-256.Also,RowContainer is used for SkewJoin.So in
rowcontainer.java,the function "copyToDFSDirecory" is defined to copy tmpfile
to hdfs path.However,the temp path generated by sha-256 is more security than
md5 which help to hold the tmppath unique and security
> Use SHA-256 for RowContainer to improve security
