-----------------------------------
Summary: 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
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.
