HCatalog多个SLF4J绑定错误消息

Question

as Im following a tutorial on hadoop ( http://hortonworks.com/hadoop-tutorial/hello-world-an-introduction-to-hadoop-hcatalog-hive-and-pig/ ) I cannot create a table using a downloaded data file as I get this error message:

HCatClient error on create table: {"statement":"use default; create table nyse_stocks( exchange string, stock_symbol string, date string, stock_price_open float, stock_price_high float, stock_price_low float, stock_price_close float, stock_volume bigint, stock_price_adj_close float) row format delimited fields terminated by '\\t';","error":"unable to create table: nyse_stocks","exec":{"stdout":"","stderr":"SLF4J: Class path contains multiple SLF4J bindings.\\nSLF4J: Found binding in [jar:file:/usr/hdp/2.2.0.0-913/hadoop/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]\\nSLF4J: Found binding in [jar:file:/usr/hdp/2.2.0.0-913/hive/lib/hive-jdbc-0.14.0.2.2.0.0-913-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class]\\nSLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.\\nSLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]\\n Command was terminated due to timeout(60000ms).

could someone please help me out in easy language and bear with me that I am a beginner,

thanks in advance!

Answer 1

Of the 2 SLF4J bindings being listed in the warning you'll need to exclude one of them from the classpath.

Even though this is a warning SLF4J will pick one logging framework/implementation and bind with it - binding is determined by the JVM and is mostly considered a random function.
