Sean Mackrory created HDFS-10797: ------------------------------------ Summary: Disk usage summary of snapshots causes renamed blocks to get counted twice Key: HDFS-10797 URL: https://issues.apache.org/jira/browse/HDFS-10797 Project: Hadoop HDFS Issue Type: Bug Reporter: Sean Mackrory
DirectoryWithSnapshotFeature.computeContentSummary4Snapshot calculates how much disk usage is used by a snapshot by tallying up the files in the snapshot that have since been deleted (that way it won't overlap with regular files whose disk usage is computed separately). However that is determined from a diff that shows moved (to Trash or otherwise) or renamed files as a deletion and a creation operation that may overlap with the list of blocks. Only the deletion operation is taken into consideration, and this causes those blocks to get represented twice in the disk usage tallying. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
