|
|

|
|
问题原因：由于 OMPUB-1479 问题，YGN-MYTEL 站点的非结构化日志成倍增加，导致 HBase 内存不足，从而引发内存溢出并导致重启。
|
|||
|
|
解决方案：减少YGN-MYTEL站点 HBase 写缓存的大小。登录Hbase集群第一台做如下操作：
|
|||
|
|
* 将 /opt/tsg/olap/hbase/conf/hbase-site.xml 文件中的 hbase.hregion.memstore.flush.size 参数值修改为 268435456。
|
|||
|
|
* 将/opt/tsg/olap/hbase/conf/hbase-site.xml分发至其他Hbase节点。
|
|||
|
|
* 在每台服务器上执行：“docker restart HRegionServer”。
