-----------------------------------

             Summary: Several HConstant members are assignable
                 Key: HBASE-12517
                 URL: https://issues.apache.org/jira/browse/HBASE-12517
             Project: HBase
          Issue Type: Bug
            Reporter: Sean Busbey
            Priority: Critical


Several of the members in HConstants are not marked final.

Generate up-to-date list with command:
0.98+
{code}
for line in "`grep -e '^ *public' hbase-common/src/main/java/org/apache/hadoop/hbase/HConstants.java | grep -v final`"; do echo "${line}" | grep -o -e " [A-Z_][A-Z_]* "; done
{code}

0.94:
{code}
for line in "`grep -e '^ *public' src/main/java/org/apache/hadoop/hbase/HConstants.java | grep -v final`"; do echo "${line}" | grep -o -e " [A-Z_][A-Z_]* "; done
{code}

These mutable versions have been in many releases. We correctly don't assign to them in our codebase, but there's no way to know if anyone does downstream.

HConstants is IA.Public and IS.Stable, but I'm fairly certain this behavior was unintentional and there isn't a non-broken use for it.
