Description:
The good summary of the issue and provided resolution can be found in this
article:
https://community.hortonworks.com/articles/105802/time-delayed-hbase-performance-degradation-with-ja.html
In a few words, due to internal JVM 7 bug (which has been addressed only in
Java 8), HotSpot code cache can become full and after that ALL JIT compilations
get suspended indefinitely. The default value for code cache size in JVM 7 is
quite low: 48MB. It is recommended to increase this value at least to 256MB
(default in JVM 8).
This BUG affects only 1.x
