1. yarn 日志列表
yarn application -list
2. impala-shell
impala-shell -q 'invalidate metadata' ## impala-shell -i node "invalidate"
3. Ozzie 调用shell
which impala-shell 获得impala-shell的路径
然后写一个shell文件:
#!/bin/bash export PYTHON_EGG_CACHE=./myeggs /usr/bin/impala-shell -q 'invalidate metadata' ##/usr/bin 是命令的路径
