ESStorageHandler was the name used in es-hadoop 1.3 Beta1 - in 2.0, the name
was changed to EsStorageHandler.
In case you are using the wrong class, you would get a ClassNotFound Exception - assuming you don't have 1.3 in your
classpath.
Regarding the error, yes, for some reason Hive since 0.12 or 0.13 is using an illegal XML character for comments which
create an invalid
XML file. There is an issue in Hive about this but it looks to be ignored [1]
Somebody (or maybe it was you) raised an issue on es-hadoop [2] to try and address the bug in Hive (for our own tests we
try to "fix" the invalid file) since it seems to not be working anymore however it's unclear to what degree this will be
possible since it's an issue in Hive itself not es-hadoop...

Hi Costin,
Actually even that issue is resolved JThere is spelling difference in the
sample available on the web, all of them have
the storage class as “EsStorageHandler” however only your GitHub post says it
is “ESStorageHandler” which is right
(https://gist.github.com/costin/8025827) ! The error should have been more
accurate if I am using a wrong class name.
Now the next problem, the MapReduce job is failing for some reason. I am still
a beginner in Hadoop so not exactly sure
where to debug. Here are some logs, looks like some bad character “&#” in the
job.xml file. But I that is generated by
Hive right ?

Hi Costin,
thanks for your response. I tried all the cleanup but still no luck :-(
Here are the steps I tried
1. Removed the es-hadoop 2.1.x completed from the server
2. Updated the hive-site.xml as below, but didn't work
<property>
<name>hive.aux.jars.path</name>
<value>/apps/sas/elasticsearch-hadoop-2.0.2/dist/elasticsearch-hadoop-2.0.2.jar</value>
<description>A comma separated list (with no spaces) of the jar
files</description>
</property>
3. Added the jar file in the hiveconf as below, still the same issue
hive --hiveconf
hive.aux.jars.path=/apps/sas/elasticsearch-hadoop-2.0.2/dist/elasticsearch-hadoop-2.0.2.jar
4. Tried adding the jar file in the hive session, still didn't work
add jar
/apps/sas/elasticsearch-hadoop-2.0.2/dist/elasticsearch-hadoop-2.0.2.jar;
I agree that both the classes are in the same package so ideally this issue
shouldn't be coming. One thing I didn't
understand from your suggestion is, why do I need to add the es-hadoop.jar
in the Hadoop classpath ? I added it to
only Hive classpath as per below URL
http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/hive.html#_installation_3
<http://www.elasticsearch.org/guide/en/elasticsearch/hadoop/current/hive.html#_installation_3>
Thanks

Hi,
The issue is most likely caused by two different versions of es-hadoop
within your classpath, probably es-hadoop
2.0.x
(2.0.2)
and 2.1.x (2.1.0.Beta3). If they are picked up by Hive or Hadoop it
means the JVM will have two jars with
classes under
the same package name.
This leads to weird conflicts as classes from jar can interact with
classes from the other jar, especially as
between
2.0.x/2.1.x the code internally
went through major changes.
Make sure you have only one version of es-hadoop in your classpath -
both on the client and in the cluster. That
includes the Hive classpath, Hadoop classpath
as well as the submitting jar (since the library might be embedded).
P.S. IllegalAccesException indicates an illegal call - such as calling
a non-public class in a different class.
However
in this case both classes are in the same
package and HiveUtils class is not private...
Cheers,
