This leaves the the index row in the unverified status. Then t= he read repair detects this unverified row when it is scanned and needs to = delete the cells of this unverified version of the row. However, the read r= epair (i.e., GlobalIndexChecker) puts the delete markers for only the cells= returned by the scan. If the scan does not return all the cells of the row= , then only a subset of the cells of the row will be deleted. The remaining= cells will not be removed and can be returned by the scans initiated later= .=C2=A0 -- This message was sent by Atlassian Jira (v8.3.4#803005)
