- 修改 control:
- 發現只相依 sun-java6-jre 會造成一些 error:
Error: could not open
`/usr/lib/jvm/java-6-sun-1.6.0.07/jre/lib/i386/jvm.cfg'
- hadoop.postinst, hadoop.postrm, hadoop.prerm
- 用來做建立 hdfsadm 使用者帳號, ssh-keygen,
ssh key exchange (authorized_keys), namenode format,
啟動 namenode, datanode, tasktracker 等

| 12 | Description: Apache Hadoop Core |
|---|
| 13 | . |
|---|
| 14 | Apache Hadoop Core is a software platform that lets one easily write and |
|---|
| 15 | run applications that process vast amounts of data. |
|---|
| 16 | . |
|---|
| 17 | Here's what makes Hadoop especially useful: |
|---|
| 18 | * Scalable: Hadoop can reliably store and process petabytes. |
|---|
| 19 | * Economical: It distributes the data and processing across clusters of |
|---|
| 20 | commonly available computers. These clusters can number into |
|---|
| 21 | the thousands of nodes. |
|---|
| 22 | * Efficient: By distributing the data, Hadoop can process it in parallel on |
|---|
| 23 | the nodes where the data is located. This makes it extremely |
|---|
| 24 | rapid. |
|---|
| 25 | * Reliable: Hadoop automatically maintains multiple copies of data and |
|---|
| 26 | automatically redeploys computing tasks based on failures. |
|---|
| 27 | . |
|---|
| 28 | Hadoop implements MapReduce, using the Hadoop Distributed File System (HDFS) |
|---|
| 29 | MapReduce divides applications into many small blocks of work. HDFS creates |
|---|
| 30 | multiple replicas of data blocks for reliability, placing them on compute |
|---|
| 31 | nodes around the cluster. MapReduce can then process the data where it is |
|---|
| 32 | located. |
|---|
| 33 | . |
|---|
