Hi all:
I got a problem when I use Hive release-0.3.0-rc1 on top of
Hadoop-0.19.1, When I followed the HiveGetingStarted to the step of
"
SELECT a.foo FROM invites a WHERE a.ds='<DATE>';
"
I got no response from hadoop, and the jobtracker seem abnormal when I
try to fresh the page of jobtracker.jsp. I use the jstack tool to get
the stack information of the jobtracker process,and I got the follow:
Found one Java-level deadlock:
=============================
"SocketListener0-7":
waiting to lock monitor 0x0000002c16f420d0 (object 0x0000002a9eedde60,
a org.apache.hadoop.mapred.JobTracker),
which is held by "IPC Server handler 6 on 9001"
"IPC Server handler 6 on 9001":

which is held by "initJobs"
"initJobs":

a org.apache.hadoop.mapred.JobTracker),
which is held by "IPC Server handler 6 on 9001"
Everytime I try to launch a hive query ,this situation happened. If I
switch to the trunk version of hive, this situation disappeared.
Please help me !
