cross space compaction


Hi all,

We find a bug which may cause data loss, and we have already submit PR to 
rel/0.12[1] and rel/0.11[2].
Because of this bug, we will release 0.12.2 and 0.11.5 soon.

Before new version released, we can set the parameter enable_unseq_compaction 
in conf/iotdb-engine.properties to false.
In this way, we can disable cross space compaction and avoid this bug.
