Add handling for WALHeaderEOFException in WALInputFormat so WALPlayer now skips empty WAL files rather than crashing. Empty WAL files (also lacking a header) either originate from crashed Region Servers, or might exist for a very short period when using the legacy WAL writer on newly created active WALs. This solves a problem where incremental backups could fail when converting WAL files to HFiles. In this use case, all WAL files passed to the WALPlayer are rolled (so no longer active), so empty WAL files were due to crashed Region Servers. (This is an updated PR of the one originally created by my colleague @thomassngdata. It applies some review remarks I had when reviewing that PR, but Thomas is currently unavailable to process them himself.) -- This is an automated message from the Apache Git Service.
