  "message": "HBASE-30346: Fix NPE in AbstractFSWAL WAL-roll debug logging aborting RegionServer (#8580)\n\nFSHLog#getPipeline() delegated directly to Hadoop\u0027s\nDFSOutputStream#getPipeline(), which can legitimately return null (streamer\nclosed, or no block pipeline currently established between blocks). The debug\nlogging added in HBASE-28775 replaced the null-tolerant Arrays.toString(...)\nwith Arrays.stream(...), which throws NPE on null, turning a benign transient\nHDFS state into a RegionServer self-abort during WAL rolling -- even though\nthe roll itself had already succeeded.\n\nNormalize FSHLog#getPipeline() to never return null (an empty array instead),\nmatching the contract AsyncFSWAL#getPipeline() already honors.\n\nSigned-off-by: Viraj Jasani \u003cvjasani@apache.org\u003e\nSigned-off by: Duo Zhang \u003czhangduo@apache.org\u003e\nSigned-off-by: Andrew Purtell \u003capurtell@apache.org\u003e\n(cherry picked from commit acc0bfc54a7da521b76c3a846880de8757cb8d96)\n",
