Winutils Windows binaries for Hadoop versions These are built directly from the same git commit used to create the official ASF releases; they are checked out and built on a windows VM which is dedicated purely to testing Hadoop/YARN apps on Windows. It is not a day-to-day used system so is isolated from driveby/email security attacks.
Jan 24, 2016 - Spark runs on Hadoop, Mesos, in the cloud or as standalone. Extract the folder containing the file winutils.exe to any location of your. Hadoop-2.7.3-src.tar.gz を入手、展開します。 [VS2012 x86 Native Tools コマンド プロンプト] または [VS2015 x86 Native Tools コマンド プロンプト] などを使い、ビルドします。.
Security: can you trust this release? • I am the Hadoop committer ' stevel': I have nothing to gain by creating malicious versions of these binaries. If I wanted to run anything on your systems, I'd be able to add the code into Hadoop itself. • I'm signing the releases.

• My keys are published on the ASF committer keylist. • The latest GPG key (E7E4 26DF 6228 1B63 D679 6A81 950C C3E0 32B7 9CA2) actually lives on a yubikey for physical security; the signing takes place there. • The same pubikey key is used for 2FA to github, for uploading artifacts and making the release. Someone malicious would need physical access to my office to sign artifacts under my name.
If they could do that, they could commit malicious code into Hadoop itself, even signing those commits with the same GPG key. Though they'd need the pin number to unlock the key, which I have to type in whenever the laptop wakes up and I want to sign something. That'd take getting something malicious onto my machine, or sniffing the bluetooth packets from the keyboard to laptop. Were someone to get physical access to my machine, they could probably install a malicous version of git, one which modified code before the checkin. I don't actually my patches to verify that there's been no tampering, but we do tend to keep an eye on what our peers put in. The other tactic would have been for a malicious yubikey to end up being delivered by Amazon to my house.
I don't have any defences against anyone going to that level of effort. 2017-12 Update That key has been revoked, though it was never actually compromised. Lack of randomness in the prime number generator on the yubikey, hence. Not set things up properly again. Note: Artifacts prior to Hadoop 2.8.0-RC3 [were signed with a different key](; again, on the ASF key list. Build Process A dedicated Windows Server 2012 VM is used for building and testing Hadoop stack artifacts. It is not used for anything else.
