Hi ,
Our environment
hbase 90.2 (10 machine)
We have 10 machine grid:
master has 48G ram
slaves machine has 16G ram.
Region Server process has 4G ram
Zookeeper process has 2G ram
We have 4map/2reducer per machine
We write from m/r job to hbase (2 jobs a day). 3 months system works
without any problem , but now every 3/4 days region server crashes.
What we done so far:
1) We running major compaction manually once a day
2) We increases regions size to prevent automatic split.
Question:
What is the way to make a HBase tuning ?
How to debug such problem , because it is still not clear for me what is
the root cause of region's crashes?
We started from this post.
