Venkatesh Seetharam commented on FALCON-623:
--------------------------------------------
I think this is handled in terms of storage but oozie needs to be setup to be
aware of both the clusters and this is documented in HiveIntegration page.
Docs:
src/site/twiki/HiveIntegration.twiki
{code}
* Oozie 4.x with Hadoop-2.x
Replication jobs are submitted to oozie on the destination cluster. Oozie runs
a table export job
on RM on source cluster. Oozie server on the target cluster must be configured
with source hadoop
configs else jobs fail with errors on secure and non-secure clusters as below:
<verbatim>
org.apache.hadoop.security.token.SecretManager$InvalidToken: Password not found
for ApplicationAttempt appattempt_1395965672651_0010_000002
</verbatim>
Make sure all oozie servers that falcon talks to has the hadoop configs
configured in oozie-site.xml
<verbatim>
<property>
<name>oozie.service.HadoopAccessorService.hadoop.configurations</name>
<value>*=/etc/hadoop/conf,arpit-new-falcon-1.cs1cloud.internal:8020=/etc/hadoop-1,arpit-new-falcon-1.cs1cloud.internal:8032=/etc/hadoop-1,arpit-new-falcon-2.cs1cloud.internal:8020=/etc/hadoop-2,arpit-new-falcon-2.cs1cloud.internal:8032=/etc/hadoop-2,arpit-new-falcon-5.cs1cloud.internal:8020=/etc/hadoop-3,arpit-new-falcon-5.cs1cloud.internal:8032=/etc/hadoop-3</value>
<description>
Comma separated AUTHORITY=HADOOP_CONF_DIR, where AUTHORITY is the
HOST:PORT of
the Hadoop service (JobTracker, HDFS). The wildcard '*' configuration
is
used when there is no exact match for an authority. The
HADOOP_CONF_DIR contains
the relevant Hadoop *-site.xml files. If the path is relative is
looked within
the Oozie configuration directory; though the path can be absolute
(i.e. to point
to Hadoop client conf/ directories in the local filesystem.
