No hash for parcel CDH-XXX.parcel.torrent
在安装 CDH 时,到 Install Parcels 这一步,分发 Parcels 一直过不去,界面一直报 Failure due to stall on seeded torrent,查看日志一直重复报 No hash
WARN scm-web-412:com.cloudera.server.web.cmf.ParcelController: No hash for parcel CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel.torrent INFO scm-web-412:com.cloudera.server.web.cmf.ParcelController: Served parcel CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel.torrent (81526 bytes) to 192.168.8.5 over PT0S. Rate: Infinity MB/s
解决方法
1.为文件生成 hash
# 查看 sha1sum /opt/cloudera/parcel-repo/CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel.torrent # 创建 vim /opt/cloudera/parcel-repo/CDH-5.16.2-1.cdh5.16.2.p0.8-el7.parcel.torrent.sha
2.关闭 IPV6
# 临时关闭 sysctl -w net.ipv6.conf.all.disable_ipv6=1 sysctl -w net.ipv6.conf.default.disable_ipv6=1 # 刷新,使设置生效 sysctl -p # 永久关闭 vim /etc/sysctl.conf net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 # 关闭指定网卡的 IPV6 # 例如对于 enp2s0f0 网卡,添加下面行 net.ipv6.conf.enp2s0f0.disable_ipv6=1
3.重启子节点服务
systemctl restart cloudera-scm-agent
