Mapr pig throwing error

Question

if I use following load command
A = LOAD '/home/mapr/resoucr' using PigStorage(',');

It throws following error:

org.apache.hadoop.conf.Configuration.deprecation - io.bytes.per.checksum is deprecated. Instead, use dfs.bytes-per-checksum

Answer 1

这些是弃用警告。可能你缺乏更新的hadoop配置。

要解决此问题，您需要更新hadoop配置文件。
