------------------------------------
Summary: Inefficient HFile format check in incremental backup
bulkload copy
Key: HBASE-30050
URL: https://issues.apache.org/jira/browse/HBASE-30050
Project: HBase
Issue Type: Bug
Reporter: Hernan Romer
IncrementalTableBackupClient.incrementalCopyBulkloadHFiles uses
HFile.isHFileFormat() to filter files before copying. This method opens each
file and reads the trailer to verify magic bytes, which requires a remote I/O
round-trip per file. For backup output directories with many files, this is
unnecessarily slow.
