如何在不使用Ctrl-C的情况下杀死hbase shell中的扫描操作 [英] How to kill a scan operation in hbase shell without Ctrl-C

问题描述

有时当我运行扫描'< tablename> 时。由于桌子很大，我看到正在打印的大量数据。我想杀死打印数据的过程。除了 Ctrl-C 以外，有没有办法做到这一点？因为 Ctrl-C 杀死了shell进程并且我不想退出shell。

解决方案

$ b scan'table'，LIMIT => 5

$

b
$ b

这将只显示5行。您也可以按ctlr + s来保存扫描，如果您已经完成了全面扫描并希望保留在特定的行上。

Sometimes when I run a scan '<tablename>. I see a continuous flood of data being printed because the table is big. I want to kill the process that print the data. Is there a way to do it other than Ctrl-C? because Ctrl-C kills the shell process and I don't want to exit the shell.

解决方案

You could use scan with LIMIT to limit the scan output on shell :

scan 'table', LIMIT => 5

This will show you only 5 rows. You could also press ctlr+s to hold the scan, if you have done a full scan and want to hold on at a specific row.
