我在试着压缩 RC 以及 ORC 文件使用 LZ4 . 我已经安装了hadoop-2.7.1和hive-1.2.1。万一 LZ4 ，我可以压缩 RC 文件没有任何问题。但是，当我尝试加载数据时 ORC 文件使用 LZ4 ，它不工作。我创造了 ORC 下表所示：

CREATE TABLE FINANCE_orc(
    PERMNO STRING,
    DATE STRING,
    CUSIP STRING,
    NCUSIP STRING,
    COMNAM STRING,
    TICKET STRING,
    PERMCO STRING,
    SHRCD STRING,
    EXCHCD STRING,
    HEXCD STRING,
    SICCD STRING,
    HSLCCD STRING,
    PRC STRING,
    VOL STRING,
    RET STRING,
    SHROUT STRING,
    DLRET STRING,
    VWRETD STRING,
    EWRETD STRING,
    SPRTRN STRING)
STORED AS ORC tblproperties ("orc.compress"="Lz4");

set mapred.output.compress=true; 
set hive.exec.compress.output=true; 
set mapred.output.compression.type = BLOCK;
set mapred.output.compression.codec=org.apache.hadoop.io.compress.GzipCodec; 
set io.compression.codecs=org.apache.hadoop.io.compress.GzipCodec; 

INSERT OVERWRITE table finance_orc select * from finance;

但在加载数据时，会出现以下错误：

我用过 Snappy 以及 Zlib 使用相同的命令，它工作正常。但问题只是 LZ4 . 我不知道为什么？
