hadoop - 配置单元失败 : ParseException line 2:0 cannot recognize input near '' macaddress '' ' CHAR' '(' in column specification

Question

我试过运行 hive -v -f sqlfile.sql

文件内容如下

CREATE TABLE UpStreamParam (
'macaddress' CHAR(50),
'datats' BIGINT,
'cmtstimestamp' BIGINT,
'modulation' INT,
'chnlidx'   INT,
'severity' BIGINT,
'rxpower'  FLOAT,
'sigqnoise' FLOAT,
'noisedeviation'  FLOAT,
'prefecber'  FLOAT,
'postfecber'  FLOAT,
'txpower'  FLOAT,
'txpowerdrop' FLOAT,
'nmter'  FLOAT,
'premtter'  FLOAT,
'postmtter'  FLOAT,
'unerroreds'  BIGINT,
'corrected'  BIGINT,
'uncorrectables'  BIGINT)
STORED AS ORC TBLPROPERTIES ("orc.compress"="SNAPPY","orc.bloom.filters.columns"="macaddress")
PARTITIONED BY ('cmtsid' CHAR(50),' date' INT)
LOCATION '/usr/hive/warehouse/UpStreamParam' ;

我收到以下错误:

FAILED: ParseException line 2:0 cannot recognize input near ''macaddress'' 'CHAR' '(' in column specification

Answer 1

首先，列名必须被`(反引号)包围，而不是'(单引号)。

因此，您必须将 'macaddress' 替换为 `macaddress`，以及所有其他列名。

其次，STORED AS和TBLPROPERTIES以及PARTITIONED BY和LOCATION的顺序是错误的。正确的顺序是PARTITIONED BY、STORED AS、LOCATION、TBLPROPERTIES。

有关详细信息，请参阅 hive 语言手册。 https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTable

所以正确的代码是

CREATE TABLE UpStreamParam (
`macaddress` CHAR(50),
`datats` BIGINT,
`cmtstimestamp` BIGINT,
`modulation` INT,
`chnlidx`   INT,
`severity` BIGINT,
`rxpower`  FLOAT,
`sigqnoise` FLOAT,
`noisedeviation`  FLOAT,
`prefecber`  FLOAT,
`postfecber`  FLOAT,
`txpower`  FLOAT,
`txpowerdrop` FLOAT,
`nmter`  FLOAT,
`premtter`  FLOAT,
`postmtter`  FLOAT,
`unerroreds`  BIGINT,
`corrected`  BIGINT,
`uncorrectables`  BIGINT)
PARTITIONED BY (`cmtsid` CHAR(50), `date` INT)
STORED AS ORC
LOCATION '/usr/hive/warehouse/UpStreamParam'
TBLPROPERTIES ("orc.compress"="SNAPPY","orc.bloom.filters.columns"="macaddress");
