Example 1 with NodeProgress

use of com.emc.vipr.model.sys.NodeProgress in project coprhd-controller by CoprHD.

the class UpgradeService method checkDownloadProgress.

/**
 * For download progress monitoring, The zookeeper structure used in the setNodeGlobalScopeInfo() and getNodeGlobalScopeInfo() is
 * /sites/(site_uuid)/config/downloadinfo/(svcId)
 * Each node has a entry in the coordinator indicated by its svcId.
 * The remote download and internode download are monitored in the same way, because the process is the same in the UpgradeImageCommon
 * class.
 * Every second if the newly downloaded bytes are more that 1MB, we update the progress entry in the coordinator.
 * For the cancel function, it first check the progress entries in the coordinator to see if there is a download in progress, if there
 * is, get the
 * version from the entry, and erase this version from the target RepositoryInfo object in the coordinator. This operation will
 * terminate the ongoing download process.
