Subject [jira] [Updated] (FALCON-1411) El expressions not getting evaluated correctly with falcon-0.7 jar
Date Wed, 19 Aug 2015 12:39:45 GMT

     [ https://issues.apache.org/jira/browse/FALCON-1411?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Pragya Mittal updated FALCON-1411:
----------------------------------
    Description: 
Following El-expressions are broken :

1. currentWeek and lastWeek 
While scheduling a process containing currentWeek/lastWeek el expression it gets scheduled
but instance keeps on waiting (although there are no missing dependency)
Process -definition is :
{code}
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<process name="Adda4dfb0-5eb92594" xmlns="uri:falcon:process:0.1">
    <clusters>
        <cluster name="Adda4dfb0-a611389d">
            <validity start="2015-02-17T10:30Z" end="2015-02-17T10:50Z"/>
        </cluster>
    </clusters>
    <parallel>1</parallel>
    <order>FIFO</order>
    <frequency>minutes(5)</frequency>
    <timezone>UTC</timezone>
    <inputs>
        <input name="inputData" feed="Adda4dfb0-04fe993c" start="currentWeek('WED',2,15)"
end="currentWeek('WED',2,25)"/>
    </inputs>
    <outputs>
        <output name="outputData" feed="Adda4dfb0-68dd6cce" instance="now(0,0)"/>
    </outputs>
    <properties>
        <property name="queueName" value="default"/>
        <property name="fileTime" value="${formatTime(dateOffset(instanceTime(), 1, 'DAY'),
'yyyy-MMM-dd')}"/>
        <property name="user" value="${user()}"/>
    </properties>
    <workflow path="/tmp/falcon-regression/ELExpCurrentAndLastWeekTest/aggregator"/>
    <retry policy="periodic" delay="minutes(3)" attempts="3"/>
    <ACL owner="pragya" group="dataqa" permission="*"/>
</process>

Oozie stack-trace is as follows :

                    <value>${dataIn('inputData', 'null')}</value>
                </property>
{code}

2. future and latest
While scheduling a process containing future/latest el expression it gets submitted but fails
on scheduling.
Falcon stack trace shows falcon is not able to communicate with oozie and gives socket timeout
exception .
