reprinted from: Hadoop Log Cleaning 1.1 Data Situation review There are two parts to the forum data: (1) Historical data of about 56GB, statistics to 2012-05-29. This also shows that before 2012-05-29, the log files were in a file, using the Append write method. (2) Since 2013-05-30, a daily data file is generated, about 150MB.

And you need to keep asking yourself: Is there a simpler way? There is to change the log format to use timesta

So far, we've configured the HA for Hadoop, so let's go through the page to see the Hadoop file system. 1. Analyze the status of active Namenode and standby namenode for client services. We can clearly see the directory structure of the Hadoop file system: Above all we are accessing Hadoop through active namenode, so if we can access Hadoop through standby namenode. Next we see that through standby namenode is inaccessible to Hadoop's file system. As prompted, we know that standby namenod
