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

             Summary: Zookeeper session ids created as unsigned long, parsed in ZooUtils.java
as signed long
                 Key: ACCUMULO-965
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-965
             Project: Accumulo
          Issue Type: Bug
          Components: start
    Affects Versions: 1.4.2
         Environment: Hadoop 0.20, ZooKeeper 3.4.3, CentOS 2.6, x64 CPU, Java 1.6.0_24
            Reporter: Rich Alberth
            Assignee: John Vines


Seems like this may be a bug.  I looked at
LiveTServerSet.assignTablet() it eventually calls Long.toHexString().
The javadoc for toHexString() says the following.
{code}Returns a string representation of the <code>long</code>
argument as an unsigned integer in base 16.
{code}

However, the method we are using to parse the Long can not handle
unsigned longs greater than MAX_LONG.  There does not seem to be a
method in long that can parse the output of  toHexString().  For
example the following will fail, any negative number will fail.

{code}Long.parseLong(Long.toHexString(-1), 16);{code}

Original Stack Dump:
{code}
