Rishav Rohit commented on FALCON-368:
-------------------------------------
hello [~samarthg] I am able to use
<property name="yday_date" value="${formatTime(dateOffset(instanceTime(), -1, 'DAY'),'yyyy-MM-dd')}"/>
in my Falcon process and pass it to Oozie SSH action. Check this thread https://mail-archives.apache.org/mod_mbox/falcon-dev/201508.mbox/ajax/%3CCAG5DmYBF%2Bw9a5aC36gwwYvVw6BM%3DoOdw2BZSwEhT2ozBrSPRPg%40mail.gmail.com%3E for details.
