【HBase工具】查看解析HFile

查看HFile是HBase本身自带的一个很实用的工具

使用也很简单：

$ ${HBASE_HOME}/bin/hbase org.apache.hadoop.hbase.io.hfile.HFile
usage: HFile [-a] [-b] [-e] [-f ] [-k] [-m] [-p] [-r ] [-v]
-a,–checkfamily Enable family check
-b,–printblocks Print block index meta data
-e,–printkey Print keys
-f,–file File to scan. Pass full-path; e.g.
hdfs://a:9000/hbase/.META./12/34
-k,–checkrow Enable row order check; looks for out-of-order keys
-m,–printmeta Print meta data of file
-p,–printkv Print key/value pairs
-r,–region Region to scan. Pass region name; e.g. ‘.META.,1’
-v,–verbose Verbose output; emits file and meta data delimiters
