Hey folks, I've been trying HBaseStorage 0.8.0 trunk with hbase-0.89 and it
does not seem to work. It gets stuck at:

[...]

the only last supported version?

    George,
    I tested it (though not very extensively) on hbase-0.89, which is what we
    run in production.
    Are you able to connect to hbase from the machine you are running pig on?

    I'm running this locally, so I have hbase and pig running on my dev box. I
    used to be able to connect just fine when running 0.20.6. We are in the
    process of migrating to 0.89 and I was testing our pig scripts which is when
    I found out that it wasn't working for me.

    Did you have to do anything special to get pig to work?

    It seems you can not get root region from zookeker.
    Could you do a simple test like following to verify whether you can
    connect to hbase ?

    public class Test{
    public static void main(String[] args) throws IOException{
    HTable table=new HTable("your_table");
    }
    }

    I can definitely connect to my local zookeeper. We have an entire app based
    on it. Only Pig cannot connect. See
    https://issues.apache.org/jira/browse/PIG-1680.

    Dmitriy, see https://issues.apache.org/jira/browse/PIG-1680 and let me know
    what you think. I don't think the current trunk can really work against
    hbase 0.89 using an HBaseStorage compiled against the hbase 0.20.6 API.
    Locally at least, a 0.20.6 client cannot connect to a 0.89 instance for me.
    We had the same issue in our application's DAOs and we had to re-compile
    them against the 0.89 API.

    Once I did that with the patch attached to PIG-1680, my pig scripts started
    working again.

    Yeah this is a real thing, thanks for providing the patch. I added some
    comments on the ticket -- I am concerned not all Pig users are ready to
    switch over to a hadoop-with-appends dependency. A shim layer may be
    required again.

    Let's continue the discussion on PIG-1680 in the Jira, yeah?

    I found out that it wasn't working for me.

    Did you have to do anything special to get pig to work?

    George,
    I tested it (though not very extensively) on hbase-0.89, which is what
    we
    run in production.
    Are you able to connect to hbase from the machine you are running pig
    on?

    Hi George

    Here's three things should been taken care when you use HBaseStorage()


    1. Register three jars: hbase-0.20.6.jar, zookeeper.jar, guava.jar
    2. Tell the TaskTracker the configuration files of hbase storage, one
    convinenit method method is copy files under $HBASE_HOME/conf to
    $HADOOP_HOMB/conf
    3. Import package org.apache.pig.backend.hadoop.hbase, or the full
    qualified class name :
    org.apache.pig.backend.hadoop.hbase.HBaseStorage

    BTW, I guess you do not do the second thing, it seems it always try to
    connect the localhost's zookeeper

    Thanks Jeff,

    My setup was working fine with pig 0.8.0 trunk and 0.20.6. Does it change
    with 0.89? I would assume that the hbase jar has to at least be different
    and trunk simply seems to include 0.20.6 under /lib.

    0.89 has deprecated a few methods and changed the way one should
    instantiate HBaseConfiguration. When we upgraded, we had to make some
    changes to our data access code to bring it up to speed.
