當生成完成一個HFile后，如果你不想因為出錯而重做數據，建議在bulkimport之前，查看一下hfile hbase提供了一個查看HFile屬性的包?org.apache.hadoop.hbase.io.hfile.HFile $hbase org.apache.hadoop.hbase.io.hfile.HFile usage: HFile [-a] [-b] [-e] [-f <arg>] [-j] [-k] [-m] [-p] [-r <arg>] [-s <arg>] [-v] -a,--checkfamily ? ? ? Enable family check -b,--printblocks ? ? ? Print block index meta data -e,--printkey ? ? ? ? ?Print keys -f,--file <arg> ? ? ? ?File to scan. Pass full-path; e.g. hdfs://a:9000/hbase/.META./12/34 -j,--json ? ? ? ? ? ? ?Print in JSON format -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 <arg> ? ? ?Region to scan. Pass region name; e.g. '.META.,,1' -s,--seekToRow <arg> ? Seek to this row and print all the kvs for this row only -v,--verbose ? ? ? ? ? Verbose output; emits file and meta data delimiters 例如使用-p打印kv，示例如下 hbase org.apache.hadoop.hbase.io.hfile.HFile -f /home/xxxxx/scan-xxxx-xxxx-xxxx-xxxx/attr/e8b8a5e0d19a4f7ca342d92d50371929 ?-p ?
