mazhengxuan commented on HBASE-30288:
-------------------------------------
I have implemented the fix and opened PR #8557:
The patch makes WALKeyValueMapper use the source-to-target table mapping for
multi-table composite keys and configures bulk HFile generation with the mapped
target table descriptors and region locators.
It also extends TestWALPlayer with a source-to-target bulk-load regression test
using a pre-split target table, so the test verifies both the target output
path and the target table region boundaries.
