Hi, I have the following row key and value (column family/column qualifier ignored):
hash(sitename) + sessionid value: duration I need to calculate the duration in a distributed environment correctly. As far as I know, I need to lock the specific row during read-write (in my case my read is only happen before the write) to ensure consistency. Previously from the HBase Definitive Guide or 0.94.15, I could see (though deprecated) RowLock lockRow(byte[] row) throws IOException; void unlockRow(RowLock rl) throws IOException; But it's seems gone with the latest API. https://hbase.apache.org/apidocs/org/apache/hadoop/hbase/client/HTableInterface.html Is there anyway I could achieve the consistency with latest HBase? Best Regards, Mingtao
