    1. COThanks, That works! Is there an explicit way to specify jar file instead of copying to ${oozie.wf.application.path}/lib/ ? ( OR ) How do i use same JAR file for 2 different Workflows without duplicating it in HDFS?

    2. CO@ThammeGowda ${oozie.wf.application.path}/lib/ can actually be a common path. The same path can be used for two workflows, so that you don't have to replicate your jars.e.g hdfs://localhost:54100/user/user1/oozie/lib can be the shared location for all the jars. This path will be set as oozie.libpath for the oozie job.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
