Hi, we are running HBase on super-low-cost HW :)
Sometimes random node goes down. And HBase needs a time to move regions
from failed RS.
What are the practices to:
1. minimize MTTR?
2. is there any possibility to gracefully handle situation when region is
not accessible for r/w?
I can just drop
I usually have a class called BaseTest that every test class extends and I
configure me logging there.
public class BaseTest {
@BeforeClass
public static void init(){
BasicConfigurator.configure();
org.apache.log4j.Logger.getRootLogger().setLevel(Level.ERROR);
}
}

Hi All,
I am using HBaseTestingUtility for JUnits of my HBase code. When
HBaseTestingUtility runs, it prints thousands of lines of logs on
console(along with some catched execptions). More than 99% of time these
logs are irrelevant.
Is there a way to suppress these logs in HBasetestingutility?
Hi Anil!
You can control what gets logged by selectively changing log levels in your
log4j.properties file for tests. For some suggestions, check out the one
used in hbase-server/src/test/resources/log4j.properties [1]:

Looks like the master server isn't running or has some problems coming up.

Hi, I have one question about HBase metrics, some of them has format like
this:
QueueCallTime_num_ops java.lang.Long = 153192
QueueCallTime_min java.lang.Long = 0
QueueCallTime_max java.lang.Long = 70
QueueCallTime_mean java.lang.Double = 0.15878766515222728
I assume that all these metrics will
