Weichen Ye created HBASE-12717:
----------------------------------
Summary: Pre-split in HBaseAdmin.create() can not find the split
point
Key: HBASE-12717
URL: https://issues.apache.org/jira/browse/HBASE-12717
Project: HBase
Issue Type: Bug
Components: Admin
Affects Versions: 0.98.6
Reporter: Weichen Ye
Priority: Critical
When we set the start key and the end key in the function:
createTable(HTableDescriptor desc, byte[] startKey, byte[] endKey, int
numRegions)
the pre-split algorithm could not find a split point between the keys like
"aaa" and "aab", "1111" and "1112".
This pre-split algorithm should be able to get split point with an additional
bytes. for example:
"aaa" and "aab", split point= "aaaP"
"1111" and "1112", split point ="1111P"
Example Code for this bug:
admin.createTable(htd, Bytes.toBytes("aaa"), Bytes.toBytes("aab"), 4);
we will get the following ERROR:
Exception in thread "main" java.lang.IllegalArgumentException: Unable to split
key range into enough regions
