HBase: How to remove corrupted hbase:meta rowkeys containing single commas

[#1]

Hi all,

I've run into an interesting issue where corrupted entries with rowkeys containing a single comma (,) were inserted into hbase:meta. These rows show up in scans, but get, delete, and deleteall operations don't work on them. Example of such a row:

ROW COLUMN+CELL
rowkey, column=info:regioninfo, timestamp=..., value=...

Attempts to remove them with the Java client and HBCK2 (fixMeta) didn't work.

Has anyone dealt with this before? Is there a safe way to remove or repair such dangling/corrupted rowkeys from hbase:meta?

In addition, I have opened this upstream issue reporting the problem: https://issues.apache.org/jira/browse/HBASE-29554

Thanks in advance for any guidance.
