hbase shell java.lang.NoClassDefFoundError: HotSpot(TM)

Hi Vikram,

What version of a JVM are you using, and what is the OS here?

Can you type "java -version" and send us the output please?

Hi Harsh,

java version "1.6.0_30"
Java(TM) SE Runtime Environment (build 1.6.0_30-b12)
Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode)
I might be missing basic steps which enable usage of hbase shell with
cloudera installation


Regards
Vikram

Vikram,

The error you are receiving is pretty odd.

Can you send us a few more outputs please?

- Does invoking "/usr/lib/hbase/bin/hbase shell" work?
-- If it does, please send output of "bash -x hbase shell"
-- If it does not, please send output of "bash -x
/usr/lib/hbase/bin/hbase shell"

- Can you send us /etc/hbase/conf/hbase-env.sh contents?

Harsh,

First suggestion didn't work so I tried second . It yield in error
but gave following output This is just partial output . I have colored what
I think might be causing issue?

Vikram,

Many thanks for sending these in.

The issue is the occurrence of this message in the midst of generating
a library path.
/usr/lib/hadoop/lib/native:/usr/lib/hbase/bin/../lib/native/Linux-amd64-64'
'!=' x ']'

It looks to me like you have some bad arguments added to either
/etc/hadoop/conf/hadoop-env.sh or to /etc/hbase/conf/hbase-env.sh (One
of the -X JVM properties). Can you share the contents of these two
files?

Harsh,

But hbase and hdfs both are running fine without any issues . Only shell
is not able to start up.

I was even able to start rest connector for Hbase. But I have pasted both
env.sh files here.

Yes this problem may not affect the service uptimes but you may
currently be running without any native codec support accidentally
(possibly)

This is the erroneous line in hadoop-env.sh thats setting an invalid
MaxNewSize, leading to a JVM warn and a script run failure thats
eventually boiling down to a hbase shell invocation failure:

export HADOOP_OPTS="-Djava.net.preferIPv4Stack=true -XX:NewSize=64m
-XX:MaxNewSize=256m $HADOOP_OPTS"

Please remove it away/comment it and retry. The MaxNewSize should not
be close to the heap size. Why have you added this line btw?

Yup it worked.

Actually we wanted to run hadoop cluster with tap on maximum memory usage
by any hadoop related service. Currently we have many applications
including datanode, hbase master, hbase region server on machine with only
4GB physical memory . So I was experimenting with that parameter.

Reards,
Vikram

Could you please suggest ways to restrict hadoop, hbase services' memory
usage?

Regards,
Vikram

Vikram,

Glad to know it worked. For controlling max memory usage, you may only
need to tweak the JVM maximum heap properties for each service.

In Cloudera Manager, this is doable by editing the "Java Heap Size"
style properties in the configuration page of any service. Set it to
the bytes of memory you want it to use and save - it will validate
your configs automatically if its too low.

I used similar settings to do it after all .Thank you very much for
providing help on this issue

Regards,
Vikram
