Li Ping Zhang commented on HBASE-7119:
--------------------------------------
Yes, Stack and Jimmy, it is a failure when running the UT with non-SUN JDK(like
IBM). This issue is due to different implementation of ConcurrentHashMap and
ArraryList between different JVM vendors(like IBM jdk, SUN jdk). The solution
is to modify src/main/java/org/apache/hadoop/hbase/util/ClassSize.java, and set
CONCURRENT_HASHMAP and ARRAYLIST to the right size with the right JVM vendor. I
have fixed it with a patch, and have tested it with UT successfully, and also
run full UT to ensure the patch doesn't cause any new issue. I can work with
fixing this JIRA if it is needed.
