Using PHP to implement the operation of HDFs

Using PHP to implement the operation of HDFs, the following steps are generally as follows:

wget https://dist.apache.org/repos/dist/release/thrift/0.9.0/thrift-0.9.0.tar.gz    
Tar zxvf thrift-0.9.0.tar.gz    
CD thrift-0.9.0 Find    
/-name ' bootstrap.sh '
yum install Automake Libtool Flex Bison pkgconfig gcc-c++ boost-d Evel Libevent-devel zlib-devel python-devel ruby-devel   
/tmp/thrift-0.9.0/contrib/fb303/bootstrap.sh    
./ Configure-prefix=/usr/local/thrift make    
//installation network is not interrupted make    
install    
cp-r./lib/php//usr/local/thrift/ lib/    
cp-r/tmp/hadoop-1.0.4/src/contrib/thriftfs/gen-php//usr/local/thrift/lib/php/src/packages/hadoopfs/    
CD./lib/php/src/ext/thrift_protocol/    
yum install php-devel    
/usr/bin/phpize    
./configure Make to    
test make    
install    
Vim/etc/php.ini    
cd/tmp/hadoop-1.0.4/src/contrib/thriftfs/ scripts/    
/tmp/hadoop-1.0.4/src/contrib/thriftfs/scripts/start_thrift_server.sh

After modifying the/tmp/hadoop-1.0.4/src/contrib/thriftfs/scripts/start_thrift_ After the top and classpath rows in the server.sh file, even the thrift version has been replaced to 0.2.0 with the following error (the result of running the 21 lines above).

Look up some methods from the Internet (including modifying/tmp/hadoop-1.0.4/conf/log4j.properties files and putting log4j.appender.eventcounter= Org.apache.hadoop.log.metrics.EventCounter replaced with log4j.appender.eventcounter= Org.apache.hadoop.log.metrics.jvm.EventCounter) Try it all.

Since other people's can, their own but can not. Then consider the software environment problem. The operating system that hosts Hadoop should not be very related. What's possible is the version of Hadoop and the version of the Java SDK.
