[jira] [Updated] (HDFS-5304) Expose if a block replica is cached in getFileBlockLocations
[ https://issues.apache.org/jira/browse/HDFS-5304?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Andrew Wang updated HDFS-5304: -- Attachment: hdfs-5304-3.patch Thanks for the review Colin. Updated patch which removes the additional cached locations from PB/PB translators and does a precondition check. It should be compatible to add it back in later.

Added a boolean array to {{LocatedBlock}} which indicates if the location at the same index is cached. Added new checks to an existing test to validate.
