yarn - Hadoop: how to set HADOOP_YARN_HOME correctly -

-

i'm trying setup hadoop yarn.

the default yarn.application.classpath property set this. yarn.application.classpath

<value>    $hadoop_conf_dir,    $hadoop_common_home/*,$hadoop_common_home/lib/*,    $hadoop_hdfs_home/*,$hadoop_hdfs_home/lib/*,    $hadoop_mapred_home/*,$hadoop_mapred_home/lib/*,    $hadoop_yarn_home/*,$hadoop_yarn_home/lib/*, </value>

with configuration mr jobs failing. if substitute (hadoop_yarn_home substituted value) works fine.

<name>yarn.application.classpath</name> <value>    $hadoop_conf_dir,    $hadoop_common_home/*,$hadoop_common_home/lib/*,    $hadoop_hdfs_home/*,$hadoop_hdfs_home/lib/*,    $hadoop_mapred_home/*,$hadoop_mapred_home/lib/*,    /usr/lib/hadoop-yarn/*,/usr/lib/hadoop-yarn/lib/*, </value>

so, suspect resourcemanager has incorrect value of $hadoop_yarn_home set somewhere. i've tried setting in yarn-env.sh, hadoop-env.sh , /etc/default/hadoop-yarn, jobs keep failing.

my question is, have set $hadoop_yarn_home variable?

p.d. i'm using cdh5.

you can set configuration variables in .bashrc files belonging specific user. hope help.

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
