["Thomas D'Silva (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PHOENIX-4893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16700920#comment-16700920 ] 

Thomas D'Silva commented on PHOENIX-4893:
-----------------------------------------

[~lhofhansl]  ViewFinder.findRelatedViews() is also called when we resolve a view or a view index. As part of PHOENIX-3534 we no longer store the parent table column metadata along with the view or view index metadata. When we make a call to the server to fetch the PTable of a view or a view index we will do a point lookups on SYSTEM.CATALOG to load the ancestor column metadata.

> In a stack trace I see that phoenix.coprocessor.ViewFinder.findRelatedViews() scans SYSCAT. With splittable SYSCAT which now involves regions from other servers.
> We should really push this to the client now.
> Related to HBASE-21166
