Scylla release: version 1.4.2

The Scylla team is pleased to announce the release of Scylla 1.4.2, a bugfix release of the Scylla 1.4 stable branch. Release 1.4.2, like all past and future 1.x.y releases, is backward compatible and supports rolling upgrades.

The following bugs were fixed in this release:

  • Scylla may terminate if internal query to Authentication table does not reach the required consistency level with a non-default authentication setting (for example when a node is down) #1718
  • Scylla may not start on large machine (with many cores) when a column family has many sstables #1812
  • Scylla logs an uninformative error message for no permissions to /var/lib/scylla/ #883
  • CQL: Scylla returns an uninformative error is if keyspace replication strategy class is not found #1755
  • CQL: Using SELECT DISTINCT queries with paging can return duplicate results #1822
  • Thrift: When using SliceRange, a limit on the number of cells to return from a row was not honored #1882 (regression from Scylla 1.3)
  • Nodetool: snapshot operation may not release all of its memory back to Scylla, eventually causing an out of memory and exit #1831
  • Nodetool: nodetool info returns a negative cache capacity value #1801
  • Nodetool: when the ‘nodetool compact’ command is issued, in some circumstances, sstable file descriptors may stay open after deletion (by compaction), causing disk space to run out #1840
  • JMX: metrics (MBeans) for StorageProxy Read and Write does not return a value #1821
  • Histogram and moving average metrics return wrong values which propagate to REST, JMX API for example org.apache.cassandra.metrics.Write.Latency #1832 , #1836,#1837
  • Cache: hits during range queries do not update LRU list #1847
  • Missing SSTable summary file can cause issues from range quires failure to crashes #1857
