java.lang.Object

org.apache.hadoop.hbase.fs.HFileSystem.ReorderWALBlocks

All Implemented Interfaces:

HFileSystem.ReorderBlocks

Enclosing class:

HFileSystem

static class HFileSystem.ReorderWALBlocks
extends Object
implements HFileSystem.ReorderBlocks

We're putting at lowest priority the wal files blocks that are on the same datanode as the original regionserver which created these files. This because we fear that the datanode is actually dead, so if we use it it will timeout.
