如何通过shell脚本发送电子邮件给distcp失败？

Question

我在FOR循环中使用distcp命令将数据复制到Azure Blob存储上的多个容器。有时，特定的副本会失败。我希望在此类故障发生时获得电子邮件警报。如何获取Discp的故障日志并将其邮寄给我？

cd /var/lib/hadoop-hdfs/azcopy_linux_amd64_10.2.1/
hdfs dfs -ls hdfs://nameservice1:8020/user/securonix/snypr/resources-enriched/ | awk 'NR > 1 { print $8 }' | awk -F/ '{print "resourcegroupidpq" $8}' > parq.txt
for i in $(cat parq.txt)
   do
      ./azcopy make "https://parquet.blob.core.windows.net/$i?sv=2018-03-28&ss=bfqt&srt=sco&sp=rwdlacup&se=2919-06-29T12:00:04Z&st=2019-06-29T04:00:04Z&spr=htt"
   done
