| BUG-33843 | Tez | Log warnings or fail early if there are too many tasks for a job | |
| BUG-36601 | HBase |
Scanner keyvalue size / partial results Issue: In 2.2 clusters, setting "hbase.client.scanner.max.result.size" differently on the client side or server side might result in missed data from large scans because the scanner might wrongly assume region is exhausted before the region boundary is reached. Additionally, the result size calculation might be different if cell level tags are used even if "hbase.client.scanner.max.result.size" is the same between 2.2 and 2.3 clusters. This issue also affects rolling upgrades between 2.2 and 2.3 clusters, where a 2.2 client might miss data in a large scan when rolling upgrading or talking to 2.3 servers. As a protection, 2.3 does not set "hbase.client.scanner.max.result.size" by default. Workaround: Do not use partial scan results to be returned (by not setting "hbase.client.scanner.max.result.size") is recommended. | |
| BUG-38980 | HBASE-14223 | HBase |
Meta WALs are not split or cleared Issue: In case a meta region gets moved from one region server to another region server, the write ahead logs for the meta table might be left in the HDFS directory for the regionserver if that particular regionserver fails. This might leave the WAL files in that directory until they are removed manually, and also may result in the previous regionservers to be listed as "dead regionservers" in the master UI indefinitely. However, this is harmless and does not cause any data loss other other operational issues in HBase. |
