我发现我的hadoop节点管理器进程没有任何原因崩溃，也没有日志。
1。服务器信息
红帽企业Linux服务器版本7.2（Maipo）
hadoop 2.8.0
namenode：Intel（R）Xeon（R）CPU E5-2650 v2 @ 2.60GHz，32核，64G内存， namenode有2个节点，resourceManager / hive有1个节点
datatanode：Intel（R）Xeon（R）CPU E5-2620 v2 @ 2.10GHz，共24核，128G RAM，共5个数据节点

2。什么时候崩溃
如果我在hive中执行这些sql，一些数据节点可能会崩溃，我不知道是不是原因，但崩溃时间似乎只是在同一时间。
select max(ts) from beacon where year = 2017 and month = 6 and day >= 21
delete from beacon where ts = 1498629599829
insert into table beacon partition(year,month,day) select type,page,name,ts,year,month,day from beacon_txt where ts >= 1498629599829
第3。它崩溃时会出现什么症状
1）nodemanager进程消失
2）纱线日志中没有例外，下面结尾的datanode日志片段：

似乎java崩溃或正常退出，但没有日志。
4。信息转储
我在yarn-env.sh
中添加了一个abrt-java-connector选项YARN_OPTS =＆＃34; $ YARN_OPTS -agentpath：/usr/lib/abrt-java-connector/libabrt-java-connector.so -agentlib：abrt-java-connector = output = $ YARN_LOG_DIR / abrt-agent.log＆＃34;
