I have a test code running on my local Windows 7 machine. Note the commented code, as well, that's not making a difference.

**********Edit-1**********
I commented the created an 'uber' jar and executed the above class directly on one of the metastore servers(Linux machines), yet, the error persists.

Hello all,
hive server is listening on port 10000(tcp) and 10002(http).
If I hit, beeline -u jdbc:hive2://
It works, but when I try to access from host-ip or hostname,
It shows above errors. Anyone have idea?
1 I have created jar with custom UDF function and copied jar into dynamic.jar.dir so when I use my UDF function as part of SELECT I getting result without issues.
2 But when function is a part of WHERE clause I getting error that class of my custom function is not found.
select PK FROM "my.custom.view" where MY_FUN(ARRAY["COLF"."COL1"], 'SOMEPARAM') limit 1;

Manually adding jar with:
hdfs dfs -copyFromLocal -f /my.jar hdfs:///user/hbase/lib/my.jar
For function creation using:
CREATE FUNCTION MY_FUN(BINARY[], VARCHAR) RETURNS BOOLEAN as 'com.myCompany.phoenix.MyCustomFunction' using jar 'hdfs://localhost:57000/user/hbase/lib/my.jar';
I ran into something similar when I upgraded to Phoenix 5.0 from 4.7. I got an exception stating that I now needed to place my UDF .jar into /apps/hbase/data/lib due to permission issues. In the old environment I was able to get away using the /apps/hbase/lib directory. Maybe this is happening to you as well but it's not alerting you to the new path change.
I recently upgraded our cluster's HiveServer to HiveServer2. I also set up the Hive Metastore (in remote mode) and moved away from embedded mode (which we were previously running).
I want to test that things are properly configured and that the metatdata is acutally being stored in the remote metastore. What would be the easiest way to do this? Are their certain logs I could check to verify this behavior?
I am afraid things are not configured correctly, and I am still running my metastore in local mode, as when I query the postgresql database on the machine hosting the metastore, there are no rows in the metastore DB (despite the fact that I have created test tables through beeline).
It might be worth mentioning is that the end goal of this is to be able to query data stored in HDFS via SparkSQL. Do I need HiveServer2 to accomplish this? Apologies, I am new to a lot of this technology.

I know that this is one of the topic that's asked much. Still after I digged into all of the topics I could find (most of them talking about CLASSPATH), I cant solve mine.
Examples of the topics I found and tried:
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration
java.lang.NoClassDefFoundError with HBase Scan
I'm using Hadoop 2.5.1 with HBase 0.98.11 on Ubuntu 14.04
I set up pseudo-distributed mode and running hadoop with hbase successfully. After I want to set up the full-distributed mode, jobs fail with NoClassDefFound error. I tried adding "export HADOOP_CLASSPATH=/usr/local/hbase-0.98.11-hadoop2/bin/hbase classpath" into hadoop-env (also yarn-env), still dont work.
One notice I found is if I comment the
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
I can run the jobs SUCCESSFULLY. BUT it seems that I run it on single not multi node.
Here are some of the configs:
mapred-site

In yarn-env and hadoop-env there is just as default except the HADOOP_CLASSPATH (which doesn't change things even if I add it or not..)
Here is the error trace:

Really thanks for every help sir.
With Yarn, you need to set "yarn.application.classpath" property with the classpath for your MapReduce job. "export HADOOP_CLASSPATH" would not work with Yarn.
I am planning to apply Knox to our HDP 2.2 cluster but I encountered the hiveserver2 http mode connection. I configured hive-site.xml like below:
<property>
<name>hive.server2.enable.doAs</name>
<value>true</value>
</property>
<property>
<name>fs.hdfs.impl.disable.cache</name>
<value>true</value>
</property>
<property>
<name>fs.file.impl.disable.cache</name>
<value>true</value>
</property>
<property>
<name>hive.server2.allow.user.substitution</name>
<value>true</value>
</property>
<property>
<name>hive.server2.thrift.http.path</name>
<value>cliservice</value>
<description>Path component of URL endpoint when in HTTP mode.</description>
</property>
<property>
<name>hive.server2.transport.mode</name>
<value>http</value>
</property>
<property>
<name>hive.server2.thrift.http.port</name>
<value>10010</value>
</property>
<property>
<name>hive.server2.thrift.http.min.worker.threads</name>
<value>5</value>
</property>
<property>
<name>hive.server2.thrift.http.max.worker.threads</name>
<value>100</value>
</property>
However, when I try to connect to the server via beeline, the beeline hangs. There is no exception and error messages in the log file. If I change the transport mode to "biniary", the problem is totally gone. I don't know why it happens.
What should I do for that?
