When a RegionServer crashes, it will lose its ephemeral lease in ZooKeeper...TODO
When set to true
, the default, any error
encountered splitting will be logged, the problematic WAL will be
moved into the .corrupt
directory under the hbase
rootdir
, and processing will continue. If set to
false
, the exception will be propagated and the
split logged as failed.[16]
If we get an EOF while splitting logs, we proceed with the split
even when hbase.hlog.split.skip.errors
==
false
. An EOF while reading the last log in the
set of files to split is near-guaranteed since the RegionServer likely
crashed mid-write of a record. But we'll continue even if we got an
EOF reading other than the last file in the set.[17]
[16] See HBASE-2958 When hbase.hlog.split.skip.errors is set to false, we fail the split but thats it. We need to do more than just fail split if this flag is set.
