Re: how to load TAB_SEPRATED file in hive table
It is very much about your source file. If you choose wrong separators, then hive will not parse your file correctly. There are four kinds of separators, making it possible to clearlify lines, fields, collections, and keyvalues. You can refer to the following uri on this topic. https://cwiki.apache.org/Hive/languagemanual-ddl.html#LanguageManualDDL-CreateTable On Thu, Sep 27, 2012 at 1:48 PM, yogesh dhari wrote: > Thanks Ashok :-), > > I am not so much aware about regarding storage formats in hive(I am new to > hive). > > Could you please list some of them except those. > > 1) space seprated --> FIELDS TERMINATED BY " "; > 2) Control-A seprated > FIELDS TERMINATED BY '\001' > 3) Tab septared --> FIELDS TERMINATED BY '\t' > > Please list some more. > > > Thanks & Regards > Yogesh Kumar > > > > > >> From: ashok.sa...@wipro.com >> To: user@hive.apache.org >> Subject: RE: how to load TAB_SEPRATED file in hive table >> Date: Thu, 27 Sep 2012 05:20:11 + > >> >> '\t' >> >> From: yogesh dhari [yogeshdh...@live.com] >> Sent: Thursday, September 27, 2012 10:42 AM >> To: hive request >> Subject: how to load TAB_SEPRATED file in hive table >> >> Hi all, >> >> I have a file in which records are Tab-Seprated, >> Please suggest me how to upload such file in Hive table. >> >> Like how to specify >> >> Create table XYZ (name STRING, roll INT) >> ROW FORMAT DELIMITED >> FIELDS TERMINATED BY >> >> Please suggest for "" over here. >> >> >> Thanks & Regards >> Yogesh Kumar >> >> Please do not print this email unless it is absolutely necessary. >> >> The information contained in this electronic message and any attachments >> to this message are intended for the exclusive use of the addressee(s) and >> may contain proprietary, confidential or privileged information.

Re: how to load TAB_SEPRATED file in hive table
Hi Yogesh Which ever character is the column separator in your input file , you need to provide that in FIELDS TERMINATED BY clause. Also the common storage formats supported by hive includes - Text File - Sequence File - RC File etc Regards Bejoy KS Sent from handheld, please excuse typos. -Original Message- From: yogesh dhari Date: Thu, 27 Sep 2012 11:18:17 To: hive request Reply-To: user@hive.apache.org Subject: RE: how to load TAB_SEPRATED file in hive table Thanks Ashok :-), I am not so much aware about regarding storage formats in hive(I am new to hive).
