> `hbase.hstore.flusher.count` setting to 0 breaks HMaster
> --------------------------------------------------------
>
> Key: HBASE-23702
> URL: https://issues.apache.org/jira/browse/HBASE-23702
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 2.2.3
> Environment: HBase-2.2.3
> Java openjdk 1.8.0_222
> Ubuntu 18.04
> Reporter: Ctest
> Priority: Major
> Attachments: HBASE-23702-000.patch, HBASE-ISSUEID-000.patch.txt,
> hbase-src-patch.txt
>
>
> Summary
> The configuration parameter `hbase.hstore.flusher.count` allows `0` (which
> turns out to be a bad value after I understand the source code).
> When we set `hbase.hstore.flusher.count` to 0, HMaster will fail in 200,000
> ms without any error message, but
> ```
> java.lang.RuntimeException: Master not initialized after 200000ms
> ```
>
> There’s no messages pinpointing `hbase.hstore.flusher.count` being the root
> cause.
>
> 0 means `MemStoreFlusher` is not alive. During the initialization time of
> HMaster, `isHealthy()` will be called and it will try to check if
> `MemStoreFlusher` is alive or not. However, since we set
> `hbase.hstore.flusher.count` to 0, there will be no flusher created at the
> first place, which cause`isHealthy()` to return false. As a consequence,
> HRegionServer does not enter its main loop.
>
> *How To Reproduce*
>
> The version of HBase: 2.2.3
>
> # Set the value of configuration parameter `hbase.hstore.flusher.count` to
> `0` in “conf/hbase-site.xml”
> # Start hbase by running “bin/start-hbase.sh”
> # Wait for 3-4 minutes
> # Open the log file “logs/hbase-<username>- master -<pcname>.log”
