How to fix?

Upgrade org.apache.hadoop:hadoop-common to version 0.23.4, 2.0.2-alpha or higher.

Overview

org.apache.hadoop:hadoop-common 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 Cryptographic Weakness due to an insufficient secret key length. The package generates token passwords using a 20-bit secret when Kerberos security features are enabled, which makes it easier for context-dependent attackers to crack secret keys via a brute-force attack.
