I have hadoop and hbase installed. When i run show tables comand in hive shell the following error raised.
Hive version 0.10.0
Hbase version 0.90.6
Hadoop version 1.1.2
hive> show tables;

I found where the problem comes from. Error is related to language settings of the linux box. Before launching hive export LANG=C is needful.

any idea what's going on?

I am using Hadoop-2.6.0 secured with kerberos. Installed hive server2 1.1.0 version with derby database as connectionurl, enabled security and enabled Authorization. When enabling transaction configuration, I am getting the below exception and cannot execute any queries;
Exception

So i have created a below property in hive-site.xml file as mentioned in a blog here
Configuration
<property>
<name>hive.in.test</name>
<value>true</value>
</property>
If i set the above property then getting the below exception where i am struck and unable to solve it. I cannot run any query even use mydb;

I need a solution to work ACID transactions in Hive Server2. I found two related questions but not solved my issue.

Upgrade your hive mysql metastore db with hive-txn-schema-0.14.0.mysql.sql as follows..

I have installed hadoop-2.5.0, pig 0.13.0 and HBase 0.98.6.1 in linux. When trying to run simple pig script, error occurs as
2014-10-14 16:01:54,891 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2998: Unhandled internal error. org.apache.hadoop.hbase.util.Bytes.equals([BLjava/nio/ByteBuffer;)Z

Pasted the log below...

It seems that HBase 0.98.6.1 version does not support for pig 0.13.0
So how to make it works? or which version of HBase does support for pig 0.13.0?
The root cause for this has been identified to be https://issues.apache.org/jira/browse/HBASE-6658 where it says the class "org.apache.hadoop.hbase.filter.WritableByteArrayComparable" was renamed.
You may need to re-compile using the HBase profile you're using.
The title is a bit weird as I'm having difficulties narrowing down the problem. I used my solution on Hadoop 2.0.0-cdh4.4.0 and hive 0.10 without issues.
I can't create a table using this SerDe: https://github.com/rcongiu/Hive-JSON-Serde
first try:

I can create a table with this SerDe: https://github.com/cloudera/cdh-twitter-example
I create an external table with tweets from flume. I can't do "SELECT * FROM tweets;"

I can do SELECT id, text FROM tweets;
I can do a SELECT COUNT(*) FROM tweets;
I can't self join this table:

Does anyone know how to fix this or at least show me where the problem is?
EDIT: Can it be a problem that I built the serde on a Hadoop 2.0.0-cdh4.4.0 and hive 0.10?
From what I've seen, Hive-.11+ has a bug in join with custom SerDe.
https://github.com/Esri/gis-tools-for-hadoop/issues/9
You might try the workaround of copying the JAR file containing the SerDe class, to $HIVE_HOME/lib .
(I see in your question you got ClassNotFoundException both in join and in other cases; so far the times I have encountered such were all with join.)
[Edit] Another workaround is to use HADOOP_CLASSPATH:
env HADOOP_CLASSPATH=some.jar:other.jar hive ...
[Edit] The work around applies to Hive versions 0.11 and 0.12; then 0.13 and above contain the fix for HIVE-6670.
I am trying to read hive table using PIG script but when I run a pig code to read a table in hive its giving me following error:

Hadoop version
1.1.1
Hive version
0.9.0
Pig version
0.10.0
Pig code
a = LOAD '/user/hive/warehouse/test' USING
org.apache.pig.piggybank.storage.HiveColumnarLoader('name string');
Is it due to some version mismatch ?
Why can't you use hcatalog to access hive metadata in pig?
Check this for an example
