Hadoop 갑자기 DataNode가 java.io.IOException: Premature EOF from inputStream를 반복적으로 발생시키다가 java.lang.OutOfMemoryError: Java heap space를 내면서 죽는 경우 조치방법

총관리자 2017.07.19 10:47 조회 수 : 1685

Hadoop의 각 데몬을 기동하여 정상 작동중이다가 갑자기 DataNode가 아래와 같은 오류를 내면서 죽는 경우가 있다.

원인은 Heap메모리가 부족하여 발생하는 문제이다. 이때는 아래 내용을 참조하여 HEAP사이즈를 변경하여 각서버에 반영하고 Hadoop전체를 다시

재 기동시켜서 반영해준다.

(분제가 발생하는 노드는 전체 클러스트와 메모리는 같은데 HardDisk용량이 2.5배 정도 되는데 다른 노드에 비해서 데이타 유입량이 더 많아서

동한 다른 노드와 같은 설정을 하면 이용하면서 HEAP메모리 부족현상이 발생되는것으로 보임)


1. hadoop-env.sh에서
export HADOOP_HEAPSIZE을
export HADOOP_HEAPSIZE=3000 으로 설정한다.

export HADOOP_NAMENODE_INIT_HEAPSIZE=""을
export HADOOP_NAMENODE_INIT_HEAPSIZE="2000" 으로 설정한다.


2. mapred-env.sh에서
export HADOOP_JOB_HISTORYSERVER_HEAPSIZE=1000을
export HADOOP_JOB_HISTORYSERVER_HEAPSIZE=2000 으로 설정한다.


3. yarn-env.sh에서

JAVA_HEAP_MAX=-Xmx1000m 를
JAVA_HEAP_MAX=-Xmx2000m 으로 설정한다.

# YARN_HEAPSIZE=1000을
YARN_HEAPSIZE=2000 으로 설정한다.
