Philip Thompson updated CASSANDRA-9657: --------------------------------------- Fix Version/s: 2.1.x > Hint table doing unnecessary compaction > --------------------------------------- > > Key: CASSANDRA-9657 > URL: https://issues.apache.org/jira/browse/CASSANDRA-9657 > Project: Cassandra > Issue Type: Bug > Environment: 2.1.7 > Reporter: Jan Karlsson > Priority: Minor > Fix For: 2.1.x > > > I found some really strange behaviour. During the replay of a node I found > this in the log: > {code}INFO [CompactionExecutor:7] CompactionTask.java:271 Compacted 1 > sstables to > [/var/lib/cassandra/data/system/hints-2666e20573ef38b390fefecf96e8f0c7/system-hints-ka-120,]. > 452,150,727 bytes to 452,150,727 (~100% of original) in 267,588ms = > 1.611449MB/s. 1 total partitions merged to 1. Partition merge counts were > {1:1, }{code} > This happened multiple times until the hint replay was completed and the > sstables were removed. > I tried to replicate this by just starting up a cluster in ccm and killing a > node for a few minutes. I got the same behaviour then. > {Code} > INFO [CompactionExecutor:2] CompactionTask.java:270 - Compacted 1 sstables > to > [/home/ejankan/.ccm/hint/node3/data/system/hints-2666e20573ef38b390fefecf96e8f0c7/system-hints-ka-2,]. > 65,570 bytes to 65,570 (~100% of original) in 600ms = 0.104221MB/s. 1 > total partitions merged to 1.
