Chen Liang updated HDFS-11698: ------------------------------ Attachment: HDFS-11698-HDFS-7240.003.patch Attach v003 patch to close levelDB also, thanks [~anu] for the catch. > Ozone: SCM: CLI: Add Debug command > ----------------------------------- > > Key: HDFS-11698 > URL: https://issues.apache.org/jira/browse/HDFS-11698 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ozone > Affects Versions: HDFS-7240 > Reporter: Anu Engineer > Assignee: Chen Liang > Attachments: HDFS-11698-HDFS-7240.001.patch, > HDFS-11698-HDFS-7240.002.patch, HDFS-11698-HDFS-7240.003.patch > > > This is not discussed as part of the standard command line set, since these > are internal debug only commands. > We have levelDB that stores key, value pairs and value is always binary > blobs. These binary blobs can only be decoded using protobuf classes that are > part of ozone. > We would like to add an extension to SCM CLI which allows us to convert > levelDB to SQLlite, since SQLlite would have structured data and standard SQL > will work against it. > The reason to use SQLlite instead of some dump file like json is the scale, > it is possible that some levelDB files will have millions of keys, so having > an SQL DB with proper index will make debugging much easier. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
