When using pre-2.6.1 Hadoop versions and JDK 1.8 in a Kerberos environment, HBase server can fail and abort due to Kerberos keytab relogin error. Late version of JDK 1.7 (1.7.0_80) has the problem too. Refer toHADOOP-10786for
additional details. Consider upgrading to Hadoop 2.6.1+ in this case.

Hadoop distributions based on the 2.6.x linemusthaveHADOOP-11710applied
if you plan to run HBase on top of an HDFS Encryption Zone. Failure to do so will result in cluster failure and data loss. This patch is present in Apache Hadoop releases 2.6.1+.
Hadoop 2.7.x
Hadoop version 2.7.0 is not tested or supported as the Hadoop PMC has explicitly labeled that release as not being stable. (reference theannouncement
of Apache Hadoop 2.7.0.)
