HBase MemStoreFlusher
虽与最新版0.98.7的实现已经有差异,但分析的比较好
MemeStoreFlusher在HRegionServer类中初始化。
HRegionServer实现了Runnable接口,在run方法中针对MemeStoreFlusher进行了初始化
private void initializeThreads() throws IOException {
// Cache flushing thread.
this.cacheFlusher = new MemStoreFlusher(conf, this);
...
}
启动:
this.cacheFlusher.start(uncaughtExceptionHandler);
interrupt:
if (this.cacheFlusher != null) this.cacheFlusher.interruptIfNecessary();
