Summary: Lens Metadata Not Refreshed
Key: LENS-1301
URL: https://issues.apache.org/jira/browse/LENS-1301
Project: Apache Lens
Issue Type: Bug
Reporter: tao yan
Hi Lens Developers,
I found some issues with Lens metadata. For example, I tried to create a
dimtable and failed, but Lens will create the metadata for the table. And when
I try to create it again, it complains 'table already exist', but I cannot drop
this dimtable until I run 'show dimtables'.
lens-shell>create dimtable ***/schemas/dimension1_table3.xml
failed
lens-shell>show dimtables
...
dimension1_division2
dimension1_table3
lens-shell>drop dimtable dimension1_table3
succeeded
-----------------------------
lens-shell>create dimtable
/export/home/dev_svc/lens/schemas/dimension1_table3.xml
failed
lens-shell>drop dimtable dimension1_table3
failed
lens-shell>show dimtables
...
dimension1_division2
dimension1_table3
lens-shell>drop dimtable dimension1_table3
succeeded
