hdfs namenode gc problem

Expert Contributor

One day ,my hdfs namenode accidentally shutdown.

When I analyze the log,found that

2017-09-15T08:26:55.262+0800: 1859843.345: [GC (Allocation Failure) 2017-09-15T08:26:55.262+0800: 1859843.345: [ParNew (promotion failed): 108213K- >118016K(118016K), 0.1060261 secs]2017-09-15T08:26:55.368+0800: 1859843.451: [CMS: 21025420K->3714406K(33423360K), 119.2980533 secs] 21133633K- >3714406K(33541376K), [Metaspace: 55012K->55012K(57344K)], 119.4048541 secs] [Times: user=17.19 sys=2.45, real=119.39 secs]

So I think the full gc lead the accident.

java version on my server is openjdk 1.8.

But is there a guid way to turning the jvm option??

But my openjdk version is 1.8, So I think maybe the post is too old...
