backup - hbase export row size limit -



backup - hbase export row size limit -

i want create backup of hbase table using hbase export. problem rows big , java heap space error. there parameter can give in order limit copied size in each step?

i utilize next command:

hadoop jar /usr/lib/hbase/hbase-0.90.3-cdh3u1.jar export tablename backuppathonhdfs numberofcolumnfamiliesversions

or

hbase org.apache.hadoop.hbase.mapreduce.export tablename backuppathonhdfs numberofcolumnfamiliesversions

you can utilize export tool, is, hadoop jar hbase-*-snapshot.jar export, regexp param (if starts ^) or interpreted row key prefix lastly argument. details see in source seems not yet documented (should work 0.91.0 on).

backup hbase
