我在导入 HBase 时遇到问题，使用带有 sqoop 的大型数据集，大约 500 万条记录。mapreduce 作业开始但大约 30% 后停止。然后返回以下错误信息。
我环顾四周，找到了这个链接，并通过添加来调整我的命令import -D, mapred.task.timeout=0，-m 只是试一试，但最终结果是一样的，尽管它现在仍然停留在 90%。
sqoop 导入命令是这样的。我是否遗漏了任何参数，还是需要添加到 hbase-site 或 zoo.cfg 配置文件中？
> ./sqoop import --connect import -D mapred.task.timeout=0 'jdbc:sqlserver://192.168.4.1:1433;database=dbname;user=sa;password=password' --table user --hbase-table newtable --column-family cf1 --hbase-row-key id --hbase-create-table --split-by id -m 14
