How to fix?

Upgrade org.apache.hadoop:hadoop-mapreduce-client-core to version 0.23.2 or higher.


org.apache.hadoop:hadoop-mapreduce-client-core is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models.

Affected versions of this package are vulnerable to Arbitrary User Impersonation. The Kerberos/MapReduce security functionality in Apache Hadoop as used in Cloudera CDH CDH3u0 through CDH3u2, Cloudera hadoop-0.20-sbin before 0.20.2+923.197, and other products, allows remote authenticated users to impersonate arbitrary cluster user accounts via unspecified vectors.
