# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 8502706176 bytes for committing reserved memory.
# Possible reasons:
#   The system is out of physical RAM or swap space
#   In 32 bit mode, the process size limit was hit
# Possible solutions:
#   Reduce memory load on the system
#   Increase physical memory or swap space
#   Check if swap backing store is full
#   Use 64 bit Java on a 64 bit OS
#   Decrease Java heap size (-Xmx/-Xms)
#   Decrease number of Java threads
#   Decrease Java thread stack sizes (-Xss)
#   Set larger code cache with -XX:ReservedCodeCacheSize=

原因分析

明显是由于内存不够，查看内存占用

df -h

解决

#重启hbase、hadoop
stop-hbase.sh
stop-all.sh

start-all.sh
start-hbase.sh
#清除缓存
sync ;
echo 1 >/proc/sys/vm/drop_caches
echo 2 >/proc/sys/vm/drop_caches
echo 3 >/proc/sys/vm/drop_caches
#再次查看内存占用
df -h

2、Application is added to the scheduler and is not yet activated

再次迁移快照时，任务一直停留着不动

查看web，显示如下：

Application is added to the scheduler and is not yet activated. Skipping AM assignment as cluster resource is empty. Details : 
AM Partition = <DEFAULT_PARTITION>; AM Resource Request = <memory:2048, vCores:1>; Queue Resource Limit for AM = <memory:0, vCores:0>;
 User AM Resource Limit of the queue = <memory:0, vCores:0>; Queue AM Resource Usage = <memory:0, vCores:0>;

hbase shell能正常进入，但是输入命令，报错

分析日志，发现，在反复切割1568617738890文件，那我们将这个文件删除，再重启

#停止hbase
stop-hbase.sh


#查看WALs
hdfs dfs -ls  -R /hbase/WALs
#删除WALs
hdfs dfs -rm -R /hbase/WALs
#清空zk里面的hbase
zkCli.sh
rmr /hbase 
#启动hbase

start-hbase.sh

再次jps查看

发现HRegionServer成功启动，去hbase shell里面输命令
