Hi, all
My cluster uses hbase 0.92.0.
I'm now trying to split some big regions manually. (I configured
region file size to 20G)
I ran it like this:
hbase org.apache.hadoop.hbase.util.RegionSplitter statistic_visit1 -r -o 2
Before I split, the table statistic_visit1 has only one region:
[hadoop@hadoop01 ~]$ hadoop dfs -du /hbase/statistic_visit1
Found 3 items
5161 hdfs://hadoop01:51001/hbase/statistic_visit1/.tableinfo.0000000001
0 hdfs://hadoop01:51001/hbase/statistic_visit1/.tmp
58234791267
hdfs://hadoop01:51001/hbase/statistic_visit1/e15d089574adaeacaf75fd8e1277ce2d
And after the split is done,
[hadoop@hadoop01 ~]$ hadoop dfs -du /hbase/statistic_visit1
Found 6 items
5161 hdfs://hadoop01:51001/hbase/statistic_visit1/.tableinfo.0000000001
0 hdfs://hadoop01:51001/hbase/statistic_visit1/.tmp
58234783527
hdfs://hadoop01:51001/hbase/statistic_visit1/0eae290663e59659fc728333d0b18b47
287
hdfs://hadoop01:51001/hbase/statistic_visit1/7865a928112751bcf27fce2cc8304441
80 hdfs://hadoop01:51001/hbase/statistic_visit1/_balancedSplit
58234787479
hdfs://hadoop01:51001/hbase/statistic_visit1/e15d089574adaeacaf75fd8e1277ce2d
Does the split result look fine? And how can I get more regions?
And is there any danger, if I resize the region file size setting
to a smaller value? (like 5G)
Thanks.
