- E2GC2 Paper 排版
- hadoop.nchc.org.tw 系統調校
- 2009-08-19 waue & wade 已經新增硬碟
- waue 修改 drbl-hadoop-mount-disk
- 把 /dev/sda1 掛到 /var/lib/hadoop/
- 把 /dev/sdb1 掛到 /var/lib/hadoop/cache/hadoop/mapred
- 使用 dphys-swapfile 來附掛 swap
- 設定預設 SWAP 掛載路徑
# /etc/dphys-swapfile - user settings for dphys-swapfile package # author Neil Franklin, last modification 2006.09.15 # copyright ETH Zuerich Physics Departement # use under either modified/non-advertising BSD or GPL license # this file is sourced with . so full normal sh syntax applies # where we want the swapfile to be, this is the default CONF_SWAPFILE=/var/lib/hadoop/swap # size we want to force it to be, default (empty) gives 2*RAM # CONF_SWAPSIZE=2048 ## # Give yourself three times the memory size of swap? # # mem=$(grep MemTotal /proc/meminfo |awk '{print $2}') # CONF_SWAPSIZE=$(expr $mem \* 3) #
- 將 dphys-swapfile 加入預設起始程序。
- [注意] 由於 drbl-hadoop-mount-disk 必須在 dphys-swapfile 之前執行,預設 update-rc.d script defaults 都會加到 S20,會造成 dphy-swapfile 比 drbl-hadoop-mount-disk 早執行,將造成開機後找不到 swapfile 的問題。
~$ sudo dsh -a update-rc.d dphys-swapfile defaults 90
- 設定預設 SWAP 掛載路徑
- 關閉只有 2GB 的計算節點
