turn off 100 rows limit in SQuirrelSQL 3.2.2 on Ubuntu 10.04

Programming

2012/01/04 13:42

2011/08/05 - [Programming] - Install Sqirrel SQL & create monetdb driver on Ubuntu 10.04

참고: http://codingclues.eu/2008/the-squirrel-100-rows-problem/

현재 사용 버전: SQuirrel SQL Client Version 3.2.2 on Ubuntu 10.04
원하는 작업: table dump 시 table 전체를 dump하고 싶은데 100행만 dump됨. 100 rows limit를 끄고 싶음

방법1: prefs.xml을 찾아 <SQLLimitRows> 속성을 false로 바꿈 > 윈도우즈 버전에만 있는 파일인지 찾을 수 없었음
방법2: 다음과 같이 Object Tree에서 Contents - Limit rows 체크 박스에서 체크 해제 > 결과는 같음

방법3: SQL 탭에서 SQL results - Limit rows 체크 박스의 체크 해제
약 530000 라인의 table 전체를 dump하려고 하니 제대로 되지 않음. 아마 메모리 문제 등으로 다운된 듯.

failed to restart hbase because of time synchronization

Programming/Hadoop

2011/12/08 17:42

Missing time synchronization, scm console cannot start properly. Because of time sync, I installed ntpdate like below;

2011/10/07 - [Programming] - CentOS: time syncronization in local network / setting timezone

However time sync is broken after 2 months. So, to prohibit this problem, I wrote 'crontab' on every server.

0 0 * * * /sbin/ntpdate [ntp server] > /dev/null 2>&1

Client configuration

Programming/Hadoop

2011/12/02 12:06

https://ccp.cloudera.com/display/CDHDOC/CDH3+Deployment+on+a+Cluster

1. unset current HADOOP_CONF_DIR if set

2.
$ sudo mv [conf dir path] /etc/hadoop-0.20/

3.
$ sudo update-alternatives --install /etc/hadoop-0.20/conf hadoop-0.20-conf /etc/hadoop-0.20/[conf dir name] [priority]

4. (Not sure) restart your machine (Testing on my machine with reboot, it is applied while on server without reboot, it isn't)

5. To query Hadoop configuration alternatives
$ sudo update-alternatives --display hadoop-0.20-conf

6. When running a test from eclipse, add the "-conf <path to conf dir>" option.

7. Run an example (hadoop must be installed locally)

@$ hadoop jar /usr/lib/hadoop/hadoop-*-examples.jar pi 10 100000000@

Follow the progress of the example on the console, on the cluster's "MapReduce administration page":http://[namenode]:50030/ or using the Job Browser provided by "Hue":http://[namenode]:8088/

maven: error in opening zip file

Programming

2011/11/30 16:13

Problem: seeing the message 'error: error reading .../.../...jar; error in opening zip file, it's usually jar file is bad.

Solution: installing the right jar file (http://ondra.zizka.cz/stranky/programovani/java/maven/log4j-missing-jmx-sun-deps.texy)

mvn install:install-file -Dfile=[downloaded jar file full path] -DgroupId=[group id] -DartifactId=[artifact id] -Dversion=[version] -Dpackaging=jar -DgeneratePom=true
mvn install:install-file -Dfile=/home/hchung/downloads/jtds-1.2.4.jar -DgroupId=net.sourceforge.jtds -DartifactId=jtds -Dversion=1.2.4 -Dpackaging=jar -DgeneratePom=true
