3.0.0-alpha-1
> WALPrettyPrinter: JSON output is broken/malformed
> -------------------------------------------------
>
> Key: HBASE-26464
> URL: https://issues.apache.org/jira/browse/HBASE-26464
> Project: HBase
> Issue Type: Bug
> Components: tooling
> Affects Versions: 3.0.0-alpha-1, 1.7.1, 2.4.8
> Reporter: Nihal Jain
> Assignee: Nihal Jain
> Priority: Major
>
> The JSON output of wal pretty printer is malformed and cannot be parsed.
> There are 2 major issue:
> * The writer classes and cell codec classes are added (as normal text)
> whenever a new WAL file printing starts (NOTE: WALPrettyPrinter can take
> multiple WAL files as input)
> * The edit heap size and position are outside json formatting
> These are side effects of some patches done in past which missed to cover
> json output scenarios.
> Current sample output, which is malformed JSON:
> {code:java}
> [Writer Classes: ProtobufLogWriter AsyncProtobufLogWriter
> Cell Codec Class: org.apache.hadoop.hbase.regionserver.wal.WALCellCodec
