duyanghao updated SPARK-21348:
------------------------------
Description:
There is a eventlog file in hdfs as below:
```
-rwxrwx--- 3 root supergroup 9634238709 2017-07-08 04:37
hdfs://xxxxx/shared/spark-logs/xxxxx/xxxx.lz4
```
and i start a spark history server to loading that eventlog file,but it is too
slow to get spark web ui through that spark history server.
it has requested for several hours but nothing about spark application web ui
appears in the browser
And the cpu usage of spark history server is 105.3%
total used-memory in host is 9G
The host have 48 Cores+130G Memory,enough Computing resources for spark history
server.
