Hi, guys
As we all known, kylin produce two kinds of hdfs data. One kind data is
produced by kylin server, and the other one is produced by hbase. Kylin has run
one year. It is required to switch hdfs cluster.
Q1: Do both hdfs data for hbase and dfs data for kylin server have to be
migrated together?
Q2: Where is the hdfs data dir for hbase? Where is the hdfs data dir for
kylin server?
Q3: I find hdfs working dir exists lots of data file, how to delete
useless file?
