Chen Liang reassigned HDFS-11698:
---------------------------------
Assignee: Chen Liang
> 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
>
> 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.
