Aha, it's a protocol buffers issue :). gRPC uses protobuf-java-3.x whereas that version of HBase is on protobuf-java-2.5 (if I recall correctly).

Can you please verify that the JAR file in your Gradle cache is not malformed? e.g. `jar tf C:\Users\testUser\.gradle\caches\modules-2\files-2.1\org.apache.hbase\hbase-protocol\1.1.2.2.5.0.0-1245\b037b1aff481f7dfc40f918a38005a6dce72fe49\hbase-protocol-1.1.2.2.5.0.0-1245.jar` and look for ByteStringer.class in the output.

Nice writeup @wsalazar. I think you can simplify your classpath setup by only including the /usr/hdp/current/phoenix-client/phoenix-client.jar and the XML configuration files (core-site, hdfs-site, hbase-site). The phoenix-client.jar will contain all of the classes necessary to connect to HBase using the Phoenix (thick) JDBC driver.

I did some testing and was able to verify that this is broken in 0.9.0, 0.9.3, and the tip of the development branch. I filed https://issues.apache.org/jira/browse/THRIFT-3966 if you care to watch that.

Newer version of documentation for ImportTSV -- http://hbase.apache.org/book.html#importtsv

Superb. I'm glad you got it worked out. Ambari should have done all of the above for you. It would be great if you could share the version information for your installation so we can figure out why you had to do this by hand.

@Kevin Ng, make sure you check the value of hadoop.proxyuser.HTTP.groups and hadoop.proxyuser.HTTP.hosts matches your deployment in HDFS's core-site configuration. You probably want to set the groups equal to "*" and the hosts should be a comma-separated list of FQDN's where you have PQS deployed. You can also try enabling DEBUG logging for HBase and check the RegionServer log for an error. I would imagine that you will see an error about the HTTP/FQDN principal being disallowed to impersonate your end-user connecting to PQS.

Very strange, @Kevin Ng. I'm not sure why the fix in AMBARI-16171 didn't properly update the principal and keytab in the UI. What version of Ambari are you using? Maybe you can override these properties in the "Custom hbase-site" configuration section? I don't know enough about how Ambari is supposed to work here.

This does sound like a bug in Apache Thrift, btw. I was able to reproduce this locally with a 0.9.0. I'm wondering if it also happens with the latest in the 0.9.x line.

Does your "hadoop1" user have the permission to create a directory in "/usr/hdp/2.4.2.0-258/hbase/include/thrift"? Can you try switching to a directory which is writable by your user and re-run the command?
