LoadIncrementalHFiles can't handle CFs with blooms
--------------------------------------------------
Key: HBASE-4449
URL: https://issues.apache.org/jira/browse/HBASE-4449
Project: HBase
Issue Type: Bug
Affects Versions: 0.90.4
Reporter: David Revell
When LoadIncrementalHFiles loads a store file that crosses region boundaries,
it will split the file at the boundary to create two store files. If the store
file is for a column family that has a bloom filter, then a
"java.lang.ArithmeticException: / by zero" will be raised because
ByteBloomFilter() is called with maxKeys of 0.
The included patch assumes that the number of keys in each split child will be
equal to the number of keys in the parent's bloom filter (instead of 0). This
is an overestimate, but it's safe and easy.
