Ozzie flow not able to hive-ql having UDF add command - hadoop

Question

I am creating oozie workflow where I am calling hive sqls sequentially.
First sql has simple transformation logic. While second has temporary function creation command and add lookup files commands. I am using this UDF further in sql.
ADD JAR **;
CREATE TEMPORARY FUNCTION XXXXX AS ...;
ADD FILE *;
<workflow-app xmlns="uri:oozie:workflow:0.4" name="hive-wf">
<credentials>
<credential name="hive_credentials" type="hcat">
<property>
<name>hcat.metastore.uri</name>
<value>XXXXXXXX</value>
</property>
<property>
<name>hcat.metastore.principal</name>
<value>XXXXXXXX</value>
</property>
</credential>
</credentials>
<start to="hive-1" />
<action name="hive-1" cred="hive_credentials">
<hive xmlns="uri:oozie:hive-action:0.2">
<job-tracker>XXXXXXX</job-tracker>
<name-node>XXXXXXX</name-node>
<job-xml>/XXXXXX/oozie/oozie-hive-site.xml</job-xml>
<configuration>
<property>
<name>mapred.job.queue.name</name>
<value>default</value>
</property>
</configuration>
<script>/XXXXXXX/hive_1.sql</script>
</hive>
<ok to="hive-2" />
<error to="fail" />
</action>
<action name="hive-2" cred="hive_credentials">
<hive xmlns="uri:oozie:hive-action:0.2">
<job-tracker>XXXXXXXX</job-tracker>
<name-node>XXXXXXXX</name-node>
<job-xml>/XXXXXX/oozie/oozie-hive-site.xml</job-xml>
<configuration>
<property>
<name>mapred.job.queue.name</name>
<value>default</value>
</property>
</configuration>
<script>/XXXXXXX/hive_2.sql</script>
</hive>
<ok to="end" />
<error to="fail" />
</action>
<kill name="fail">
<message>Hive failed, error message[${wf:errorMessage(wf:lastErrorNode())}]</message>
</kill>
<end name="end" />
First hql script is executed successfully. Workflow is killed while executing second hql script giving below error.
JOB[0000044-140317190624992-oozie-oozi-W] ACTION[-] E1100: Command precondition does not hold before execution, [, coord action is null], Error Code: E1100
It throws error while executing commands to ADD UDF.(ADD JAR,CREATE TEMPORARY,ADD FILE).
I searched on this error and I got some links to ignore the error !!!
But, my actual sql using hive UDF given in second Hql script is not executed.
Can you please help?

The add jar path is a local machine path.
Oozie actions are run on datanodes. There is a possibility it cannot find the jar on the datanode and hence gives an error (Check the mapreduce logs , you would find the reason)
If this is a issue, one workaround can be to put the file in HDFS and copy it to local filesytem on the datanode during execution
