题

Is it possible to increment columns in HBase based on some comparison operator atomically ? Both increments and comparisons will be done on same row.

有帮助吗？

解决方案

A checkAndIncrement method is not implemented yet in HBase. There's a ticket for it - https://issues.apache.org/jira/browse/HBASE-6712.

What's your use? Isn't it something you can do with checkAndPut ?
